|Attitudes and discrimination|
Bisexuality is romantic attraction, sexual attraction, or sexual behavior toward both males and females, or to more than one sex or gender. It may also be defined as romantic or sexual attraction to people of any sex or gender identity, which is also known as pansexuality.
The term bisexuality is mainly used in the context of human attraction to denote romantic or sexual feelings toward both men and women, and the concept is one of the three main classifications of sexual orientation along with heterosexuality and homosexuality, all of which exist on the heterosexual–homosexual continuum. A bisexual identity does not necessarily equate to equal sexual attraction to both sexes; commonly, people who have a distinct but not exclusive sexual preference for one sex over the other also identify themselves as bisexual.
Scientists do not know the exact cause of sexual orientation, but they theorize that it is caused by a complex interplay of genetic, hormonal, and environmental influences, and do not view it as a choice. Although no single theory on the cause of sexual orientation has yet gained widespread support, scientists favor biologically based theories. There is considerably more evidence supporting nonsocial, biological causes of sexual orientation than social ones, especially for males.
Bisexuality has been observed in various human societies and elsewhere in the animal kingdom throughout recorded history. The term bisexuality, however, like the terms hetero- and homosexuality, was coined in the 19th century.
Bisexuality is romantic or sexual attraction to both males and females. The American Psychological Association states that "sexual orientation falls along a continuum. In other words, someone does not have to be exclusively homosexual or heterosexual, but can feel varying degrees of both. Sexual orientation develops across a person's lifetime–different people realize at different points in their lives that they are heterosexual, bisexual or homosexual."
Sexual attraction, behavior, and identity may also be incongruent, as sexual attraction or behavior may not necessarily be consistent with identity. Some individuals identify themselves as heterosexual, homosexual, or bisexual without having had any sexual experience. Others have had homosexual experiences but do not consider themselves to be gay, lesbian, or bisexual. Likewise, self-identified gay or lesbian individuals may occasionally sexually interact with members of the opposite sex but do not identify as bisexual. The terms queer, polysexual, heteroflexible, homoflexible, men who have sex with men and women who have sex with women may also be used to describe sexual identity or identify sexual behavior.
Some sources state that bisexuality encompasses romantic or sexual attraction to all gender identities or that it is romantic or sexual attraction to a person irrespective of that person's biological sex or gender, equating it to or rendering it interchangeable with pansexuality. The concept of pansexuality deliberately rejects the gender binary, the "notion of two genders and indeed of specific sexual orientations", as pansexual people are open to relationships with people who do not identify as strictly men or women. Sometimes the phrase "bisexual umbrella" is used to describe any nonmonosexual behaviors, attractions, and identities, usually for purposes of collective action and challenging monosexist cultural assumptions.
The bisexual activist Robyn Ochs defines bisexuality as "the potential to be attracted—romantically and/or sexually—to people of more than one sex and/or gender, not necessarily at the same time, not necessarily in the same way, and not necessarily to the same degree."
According to Rosario, Schrimshaw, Hunter, Braun (2006):
...the development of a lesbian, gay, or bisexual (LGB) sexual identity is a complex and often difficult process. Unlike members of other minority groups (e.g., ethnic and racial minorities), most LGB individuals are not raised in a community of similar others from whom they learn about their identity and who reinforce and support that identity. Rather, LGB individuals are often raised in communities that are either ignorant of or openly hostile toward homosexuality.
Bisexuality as a transitional identity has also been examined. In a longitudinal study about sexual identity development among lesbian, gay, and bisexual (LGB) youths, Rosario et al. "found evidence of both considerable consistency and change in LGB sexual identity over time". Youths who had identified as both gay/lesbian and bisexual prior to baseline were approximately three times more likely to identify as gay/lesbian than as bisexual at subsequent assessments. Of youths who had identified only as bisexual at earlier assessments, 60 to 70 percent continued to thus identify, while approximately 30 to 40 percent assumed a gay/lesbian identity over time. Rosario et al. suggested that "although there were youths who consistently self-identified as bisexual throughout the study, for other youths, a bisexual identity served as a transitional identity to a subsequent gay/lesbian identity."
By contrast, a longitudinal study by Lisa M. Diamond, which followed women identifying as lesbian, bisexual, or unlabeled, found that "more women adopted bisexual/unlabeled identities than relinquished these identities," over a ten-year period. The study also found that "bisexual/unlabeled women had stable overall distributions of same-sex/other-sex attractions." Diamond has also studied male bisexuality, noting that survey research found "almost as many men transitioned at some point from a gay identity to a bisexual, queer or unlabeled one, as did from a bisexual identity to a gay identity."
Main article: Kinsey scale
In the 1940s, the zoologist Alfred Kinsey created a scale to measure the continuum of sexual orientation from heterosexuality to homosexuality. Kinsey studied human sexuality and argued that people have the capability of being hetero- or homosexual even if this trait does not present itself in the current circumstances. The Kinsey scale is used to describe a person's sexual experience or response at a given time. It ranges from 0, meaning exclusively heterosexual, to 6, meaning exclusively homosexual. People who rank anywhere from 2 to 4 are often considered bisexual; they are often not fully one extreme or the other. The sociologists Martin S. Weinberg and Colin J. Williams write that, in principle, people who rank anywhere from 1 to 5 could be considered bisexual.
The psychologist Jim McKnight writes that while the idea that bisexuality is a form of sexual orientation intermediate between homosexuality and heterosexuality is implicit in the Kinsey scale, that conception has been "severely challenged" since the publication of Homosexualities (1978), by Weinberg and the psychologist Alan P. Bell.
Main article: Demographics of sexual orientation
Scientific estimates as to the prevalence of bisexuality have varied from 0.7% to 8%. The Janus Report on Sexual Behavior, published in 1993, concluded that 5 percent of men and 3 percent of women considered themselves bisexual, while 4 percent of men and 2 percent of women considered themselves homosexual.
A 2002 survey in the United States by National Center for Health Statistics found that 1.8 percent of men ages 18–44 considered themselves bisexual, 2.3 percent homosexual, and 3.9 percent as "something else". The same study found that 2.8 percent of women ages 18–44 considered themselves bisexual, 1.3 percent homosexual, and 3.8 percent as "something else". In 2007, an article in the 'Health' section of The New York Times stated that "1.5 percent of American women and 1.7 percent of American men identify themselves [as] bisexual." Also in 2007, it was reported that 14.4 percent of young US women identified themselves as "not strictly heterosexual", with 5.6 percent of the men identifying as gay or bisexual. A study in the journal Biological Psychology in 2011 reported that there were men who identify themselves as bisexuals and who were aroused by both men and women. In the first large-scale government survey measuring Americans' sexual orientation, the NHIS reported in July 2014 that only 0.7 percent of Americans identify as bisexual.
A collection of recent Western surveys finds that about 10% of women and 4% of men identify as mostly heterosexual, 1% of women and 0.5% of men as bisexual, and 0.4% of women and 0.5% of men as mostly homosexual.:55
Across cultures, there is some variance in the prevalence of bisexual behavior, but there is no persuasive evidence that there is much variance in the rate of same-sex attraction. The World Health Organization estimates a worldwide prevalence of men who have sex with men between 3 and 16%, many of whom have sex with women as well.
In the past, many researchers have questioned whether men with bisexual arousal patterns exist, but they do.
Main article: Bisexual community
The bisexual community (also known as the bisexual/pansexual, bi/pan/fluid, or non-monosexual community) includes members of the LGBT community who identify as bisexual, pansexual or fluid. Because some bisexual people do not feel that they fit into either the gay or the heterosexual world, and because they have a tendency to be "invisible" in public, some bisexual persons are committed to forming their own communities, culture, and political movements. Some who identify as bisexual may merge themselves into either homosexual or heterosexual society. Other bisexual people see this merging as enforced rather than voluntary; bisexual people can face exclusion from both homosexual and heterosexual society on coming out. Psychologist Beth Firestein states that bisexuals tend to internalize social tensions related to their choice of partners and feel pressured to label themselves as homosexuals instead of occupying the difficult middle ground where attraction to people of both sexes would defy society's value on monogamy. These social tensions and pressure may affect bisexuals' mental health, and specific therapy methods have been developed for bisexuals to address this concern.
Bisexual behaviors are also associated in popular culture with men who engage in same-sex activity while otherwise presenting as heterosexual. The majority of such men — said to be living on the down-low — do not self-identify as bisexual. However, this may be a cultural misperception closely related to that of other LGBT individuals who hide their actual orientation due to societal pressures, a phenomenon colloquially called "being closeted".[original research?]
In the U.S., a 2013 Pew survey showed that 28% of bisexuals said that "all or most of the important people in their life are aware that they are LGBT" vs. 77% of gay men and 71% of lesbians. Furthermore, when broken down by gender, only 12% of bisexual men said that they were "out" vs. 33% of bisexual women.

Like people of other LGBT sexualities, bisexuals often face discrimination. In addition to the discrimination associated with homophobia, bisexuals frequently contend with discrimination from gay men, lesbians, and straight society around the word bisexual and bisexual identity itself. The belief that everyone is bisexual (especially women as opposed to men), or that bisexuality does not exist as a unique identity, is common. This stems from two views: In the heterosexist view, people are presumed to be sexually attracted to the opposite sex, and it is sometimes reasoned that a bisexual person is simply a heterosexual person who is sexually experimenting. In the monosexist view, it is believed that people cannot be bisexual unless they are equally sexually attracted to both sexes, regulating sexual orientation to being about the sex or gender one prefers. In this view, people are either exclusively homosexual (gay/lesbian) or exclusively heterosexual (straight), closeted homosexual people who wish to appear heterosexual, or heterosexuals who are experimenting with their sexuality. Assertions that one cannot be bisexual unless equally sexually attracted to both sexes, however, are disputed by various researchers, who have reported bisexuality to fall on a continuum, like sexuality in general.
Male bisexuality is particularly presumed to be non-existent, with sexual fluidity studies adding to the debate. In 2005, researchers Gerulf Rieger, Meredith L. Chivers, and J. Michael Bailey used penile plethysmography to measure the arousal of self-identified bisexual men to pornography involving only men and pornography involving only women. Participants were recruited via advertisements in gay-oriented magazines and an alternative paper. They found that the self-identified bisexual men in their sample had genital arousal patterns similar to either homosexual or heterosexual men. The authors concluded that "in terms of behavior and identity, bisexual men clearly exist", but that male bisexuality had not been shown to exist with respect to arousal or attraction. The assertion of Bailey that "for men arousal is orientation" was criticized by Fairness and Accuracy in Reporting (FAIR) as a simplification which neglects to account for behavior and self-identification. Further, some researchers hold that the technique used in the study to measure genital arousal is too crude to capture the richness (erotic sensations, affection, admiration) that constitutes sexual attraction. The National Gay and Lesbian Task Force called the study and The New York Times coverage of it flawed and biphobic.
The American Institute of Bisexuality stated that Bailey's study was misinterpreted and misreported by both The New York Times and its critics. In 2011, Bailey and other researchers reported that among men with a history of several romantic and sexual relationships with members of both sexes, high levels of sexual arousal were found in response to both male and female sexual imagery. The subjects were recruited from a Craigslist group for men seeking intimacy with both members of a heterosexual couple. The authors said that this change in recruitment strategy was an important difference, but it may not have been a representative sample of bisexual-identified men. They concluded that "bisexual-identified men with bisexual arousal patterns do indeed exist", but could not establish whether such a pattern is typical of bisexual-identified men in general.
Bisexual erasure (or bisexual invisibility) is the tendency to ignore, remove, falsify, or reexplain evidence of bisexuality in culture, history, academia, news media and other primary sources. In its most extreme form, bisexual erasure includes denying that bisexuality exists. It is often a manifestation of biphobia, although it does not necessarily involve overt antagonism.
There is increasing inclusion and visibility of bisexuals, particularly in the LGBT community. American psychologist Beth Firestone writes that since she wrote her first book on bisexuality, in 1996, "bisexuality has gained visibility, although progress is uneven and awareness of bisexuality is still minimal or absent in many of the more remote regions of our country and internationally."
Main article: LGBT symbols
A common symbol of the bisexual community is the bisexual pride flag, which has a deep pink stripe at the top for homosexuality, a blue one on the bottom for heterosexuality, and a purple one – blending the pink and blue – in the middle to represent bisexuality.
Another symbol with a similarly symbolic color scheme is a pair of overlapping pink and blue triangles, forming purple or lavender where they intersect. This design is an expansion on the pink triangle, a well-known symbol for the homosexual community.
Some bisexual individuals object to the use of a pink triangle, as it was the symbol that Adolf Hitler's regime use to tag and persecute homosexuals. In response, a double crescent moon symbol was devised specifically to avoid the use of triangles. This symbol is common in Germany and surrounding countries.
In Steve Lenius' original 2001 paper, he explored the acceptance of bisexuality in a supposedly pansexual BDSM community. The reasoning behind this is that "coming-out" had become primarily the territory of the gay and lesbian, with bisexuals feeling the push to be one or the other (and being right only half the time either way). What he found in 2001, was that people in BDSM were open to discussion about the topic of bisexuality and pansexuality and all controversies they bring to the table, but personal biases and issues stood in the way of actively using such labels. A decade later, Lenius (2011) looked back on his study and considered if anything has changed. He concluded that the standing of bisexuals in the BDSM and kink community was unchanged, and believed that positive shifts in attitude were moderated by society's changing views towards different sexualities and orientations. But Lenius (2011) does emphasize that the pansexual promoting BDSM community helped advance greater acceptance of alternative sexualities.
Brandy Lin Simula (2012), on the other hand, argues that BDSM actively resists gender conforming and identified three different types of BDSM bisexuality: gender-switching, gender-based styles (taking on a different gendered style depending on gender of partner when playing), and rejection of gender (resisting the idea that gender matters in their play partners). Simula (2012) explains that practitioners of BDSM routinely challenge our concepts of sexuality by pushing the limits on pre-existing ideas of sexual orientation and gender norms. For some, BDSM and kink provides a platform in creating identities that are fluid, ever-changing.
Feminist positions on bisexuality range greatly, from acceptance of bisexuality as a feminist issue to rejection of bisexuality as reactionary and anti-feminist backlash to lesbian feminism. A number of women who were at one time involved in lesbian-feminist activism have since come out as bisexual after realizing their attractions to men. A widely studied[by whom?] example of lesbian-bisexual conflict in feminism was the Northampton Pride March during the years between 1989 and 1993, where many feminists involved debated over whether bisexuals should be included and whether or not bisexuality was compatible with feminism.
Common lesbian-feminist critiques leveled at bisexuality were that bisexuality was anti-feminist, that bisexuality was a form of false consciousness, and that bisexual women who pursue relationships with men were "deluded and desperate." Tensions between bisexual feminists and lesbian feminists have eased since the 1990s, as bisexual women have become more accepted in the feminist community, but some lesbian feminists such as Julie Bindel are still critical of bisexuality. Bindel has described female bisexuality as a "fashionable trend" being promoted due to "sexual hedonism" and broached the question of whether bisexuality even exists. She has also made tongue-in-cheek comparisons of bisexuals to cat fanciers and devil worshippers. Sheila Jeffreys writes in The Lesbian Heresy that while many feminists are comfortable working alongside gay men, they are uncomfortable interacting with bisexual men. Jeffreys states that while gay men are unlikely to sexually harass women, bisexual men are just as likely to be bothersome to women as heterosexual men.
Donna Haraway was the inspiration and genesis for cyberfeminism with her 1985 essay "A Cyborg Manifesto: Science, Technology, and Socialist-Feminism in the Late Twentieth Century" which was reprinted in Simians, Cyborgs and Women: The Reinvention of Nature (1991). Haraway's essay states that the cyborg "has no truck with bisexuality, pre-oedipal symbiosis, unalienated labor, or other seductions to organic wholeness through a final appropriation of all powers of the parts into a higher unity."
A bisexual woman filed a lawsuit against the magazine Common Lives/Lesbian Lives, alleging discrimination against bisexuals when her submission was not published.
Main article: History of bisexuality
Ancient Greeks and Romans did not associate sexual relations with well-defined labels, as modern Western society does. Men who had male lovers were not identified as homosexual, and may have had wives or other female lovers.
Ancient Greek religious texts, reflecting cultural practices, incorporated bisexual themes. The subtexts varied, from the mystical to the didactic. Spartans thought that love and erotic relationships between experienced and novice soldiers would solidify combat loyalty and unit cohesion, and encourage heroic tactics as men vied to impress their lovers. Once the younger soldiers reached maturity, the relationship was supposed to become non-sexual, but it is not clear how strictly this was followed. There was some stigma attached to young men who continued their relationships with their mentors into adulthood. For example, Aristophanes calls them euryprôktoi, meaning "wide arses", and depicts them like women.
Similarly, in ancient Rome, gender did not determine whether a sexual partner was acceptable, as long as a man's enjoyment did not encroach on another's man integrity. It was socially acceptable for a freeborn Roman man to want sex with both female and male partners, as long as he took the penetrative role. The morality of the behavior depended on the social standing of the partner, not gender per se. Both women and young men were considered normal objects of desire, but outside marriage a man was supposed to act on his desires only with slaves, prostitutes (who were often slaves), and the infames. It was immoral to have sex with another freeborn man's wife, his marriageable daughter, his underage son, or with the man himself; sexual use of another man's slave was subject to the owner's permission. Lack of self-control, including in managing one's sex life, indicated that a man was incapable of governing others; too much indulgence in "low sensual pleasure" threatened to erode the elite male's identity as a cultured person.
Alfred Kinsey conducted the first large surveys of homosexual behavior in the United States during the 1940s. The results shocked the readers of his day because they made same-sex behavior and attractions seem so common. His 1948 work Sexual Behavior in the Human Male stated that among men "nearly half (46%) of the population engages in both heterosexual and homosexual activities, or reacts to persons of both sexes, in the course of their adult lives" and that "37% of the total male population has at least some overt homosexual experience to the point of orgasm since the onset of adolescence." Kinsey himself disliked the use of the term bisexual to describe individuals who engage in sexual activity with both males and females, preferring to use bisexual in its original, biological sense as hermaphroditic, stating, "Until it is demonstrated [that] taste in a sexual relation is dependent upon the individual containing within his anatomy both male and female structures, or male and female physiological capacities, it is unfortunate to call such individuals bisexual." Although more recent researchers believe that Kinsey overestimated the rate of same-sex attraction,:9:147 his work is considered pioneering and some of the most well known sex research of all time.:29
Main article: Media portrayals of bisexuality
Bisexuality tends to be associated with negative media portrayals; references are sometimes made to stereotypes or mental disorders. In an article regarding the 2005 film Brokeback Mountain, sex educator Amy Andre argued that in films, bisexuals are often depicted negatively:
I like movies where bisexuals come out to each other together and fall in love, because these tend to be so few and far between; the most recent example would be 2002's lovely romantic comedy, Kissing Jessica Stein. Most movies with bi characters paint a stereotypical picture.... The bi love interest is usually deceptive (Mulholland Drive), over-sexed (Sex Monster), unfaithful (High Art), and fickle (Three of Hearts), and might even be a serial killer, like Sharon Stone in Basic Instinct. In other words, the bisexual is always the cause of the conflict in the film.— Amy Andre, American Sexuality Magazine
Using a content analysis of more than 170 articles written between 2001 and 2006, sociologist Richard N. Pitt, Jr. concluded that the media pathologized black bisexual men's behavior while either ignoring or sympathizing with white bisexual men's similar actions. He argued that the black bisexual man is often described as a duplicitous heterosexual man spreading the HIV/AIDS virus. Alternatively, the white bisexual man is often described in pitying language as a victimized homosexual man forced into the closet by the heterosexist society around him.
In 1914 the first documented appearance of bisexual characters (female and male) in an American motion picture occurred in A Florida Enchantment, by Sidney Drew. However, under the censorship required by the Hays Code, the word bisexual could not be mentioned, and almost no bisexual characters appeared in American film from 1934 until 1968.
Notable and varying portrayals of bisexuality can be found in mainstream movies such as Black Swan (2010), Frida (2002), Showgirls (1995), The Pillow Book (1996), Alexander (2004), The Rocky Horror Picture Show (1975), Henry & June (1990), Chasing Amy (1997), Velvet Goldmine (1998), Kissing Jessica Stein (2001), The Fourth Man (1993), Basic Instinct (1992), Mulholland Drive (2001), Sunday Bloody Sunday (1971), Something for Everyone (1970), The Rules of Attraction (2002), Brokeback Mountain (2005), and Call Me by Your Name (2017).
Virginia Woolf's Orlando: A Biography (1928) is an early example of bisexuality in literature. The story, of a man who changes into a woman without a second thought, was based on the life of Woolf's lover Vita Sackville-West. Woolf used the gender switch to avoid the book being banned for homosexual content. The pronouns switch from male to female as Orlando's gender changes. Woolf's lack of definite pronouns allows for ambiguity and lack of emphasis on gender labels. Her 1925 book Mrs Dalloway focused on a bisexual man and a bisexual woman in sexually unfulfilled heterosexual marriages in later life. Following Sackille-West's death, her son Nigel Nicolson published Portrait of a Marriage, one of her diaries recounting her affair with a woman during her marriage to Harold Nicolson. Other early examples include works of D.H. Lawrence, such as Women in Love (1920), and Colette's Claudine (1900–1903) series.
The main character in Patrick White's novel, The Twyborn Affair (1979), is bisexual. Contemporary novelist Bret Easton Ellis' novels, such as Less Than Zero (1985) and The Rules of Attraction (1987) frequently feature bisexual male characters; this "casual approach" to bisexual characters recurs throughout Ellis' work.
Rock musician David Bowie famously declared himself bisexual in an interview with Melody Maker in January 1972, a move coinciding with the first shots in his campaign for stardom as Ziggy Stardust. In a September 1976 interview with Playboy, Bowie said, "It's true—I am a bisexual. But I can't deny that I've used that fact very well. I suppose it's the best thing that ever happened to me." In a 1983 interview, he said it was "the biggest mistake I ever made", elaborating in 2002 he explained "I don't think it was a mistake in Europe, but it was a lot tougher in America. I had no problem with people knowing I was bisexual. But I had no inclination to hold any banners or be a representative of any group of people. I knew what I wanted to be, which was a songwriter and a performer [...] America is a very puritanical place, and I think it stood in the way of so much I wanted to do."
Queen singer Freddie Mercury was also open about his bisexuality, though he did not publicly discuss his relationships.
In 1995, Jill Sobule sang about bi-curiosity in her song "I Kissed a Girl", with a video that alternated images of Sobule and a boyfriend along with images of her with a girlfriend. Another song with the same name by Katy Perry also hints at the same theme. Some activists suggest the song merely reinforces the stereotype of bisexuals experimenting and of bisexuality not being a real sexual preference. Lady Gaga has also stated that she is bisexual, and has acknowledged that her song "Poker Face" is about fantasizing about a woman while being with a man.
Brian Molko, lead singer of Placebo, is openly bisexual. Green Day frontman Billie Joe Armstrong has also identified himself as bisexual, saying in a 1995 interview with The Advocate, "I think I've always been bisexual. I mean, it's something that I've always been interested in. I think people are born bisexual, and it's just that our parents and society kind of veer us off into this feeling of 'Oh, I can't.' They say it's taboo. It's ingrained in our heads that it's bad, when it's not bad at all. It's a very beautiful thing." In 2014 Armstrong discussed songs such as "Coming Clean" stating, "It was a song about questioning myself. There are these other feelings you may have about the same sex, the opposite sex, especially being in Berkeley and San Francisco then. People are acting out what they're feeling: gay, bisexual, transgender, whatever. And that opens up something in society that becomes more acceptable. Now we have gay marriage becoming recognized... I think it's a process of discovery. I was willing to try anything."
In the Netflix original series Orange is the New Black the main character, Piper Chapman, played by actress Taylor Schilling, is a bisexual female inmate who is shown having relationships with both men and women. In season one, before entering the prison, Piper is engaged to male fiancé Larry Bloom, played by actor Jason Biggs. Then, upon entering the prison, she reconnects with former lover (and fellow inmate), Alex Vause, played by Laura Prepon. Another character who is portrayed as bisexual in the show is an inmate named Lorna Morello, played by actress Yael Stone. She has an intimate relationship with fellow inmate Nicky Nichols, played by Natasha Lyonne, while still yearning for her male "fiance", Christopher MacLaren, played by Stephen O'Reilly.
The FOX television series House features a bisexual female doctor, Remy "Thirteen" Hadley, played by Olivia Wilde, from season four onwards. The same network had earlier aired the television series The O.C., which for a time featured bisexual Alex Kelly (also played by Olivia Wilde), the local rebellious hangout spot's manager, as a love interest of Marissa Cooper. In the HBO drama Oz, Chris Keller was a bisexual serial killer who tortured and raped various men and women. Other films in which bisexual characters conceal murderous neuroses include Black Widow, Blue Velvet, Cruising, Single White Female, and Girl, Interrupted.
Beginning with the 2009 season, MTV's The Real World series featured two bisexual characters, Emily Schromm, and Mike Manning.
The Showcase supernatural crime drama, Lost Girl, about creatures called Fae who live secretly among humans, features a bisexual protagonist, Bo, played by Anna Silk. In the story arc she is involved in a love triangle between Dyson, a wolf-shapeshifter (played by Kris Holden-Ried), and Lauren Lewis, a human doctor (played by Zoie Palmer) in servitude to the leader of the Light Fae clan.
In the BBC TV science fiction show Torchwood, several of the main characters appear to have fluid sexuality. Most prominent among these is Captain Jack Harkness, a pansexual who is the lead character and an otherwise conventional science fiction action hero. Within the logic of the show, where characters can also interact with alien species, producers sometimes use the term "omnisexual" to describe him. Jack's ex, Captain John Hart, is also bisexual. Of his female exes, significantly at least one ex-wife and at least one woman with whom he has had a child have been indicated. Some critics draw the conclusion that the series more often shows Jack with men than women. Creator Russell T Davies says one of pitfalls of writing a bisexual character is you "fall into the trap" of "only having them sleep with men." He describes of the show's fourth series, "You'll see the full range of his appetites, in a really properly done way." The preoccupation with bisexuality has been seen by critics as complementary to other aspects of the show's themes. For heterosexual character Gwen Cooper, for whom Jack harbors romantic feelings, the new experiences she confronts at Torchwood, in the form of "affairs and homosexuality and the threat of death", connote not only the Other but a "missing side" to the Self. Under the influence of an alien pheromone, Gwen kisses a woman in Episode 2 of the series. In Episode 1, heterosexual Owen Harper kisses a man to escape a fight when he is about to take the man's girlfriend. Quiet Toshiko Sato is in love with Owen, but has also had brief romantic relationships with a female alien and a male human.
In October 2009, "A Rose By Any Other Name" was released as a "webisode" series on YouTube. Directed by bisexual rights advocate Kyle Schickner, the plot centers around a lesbian-identified woman who falls in love with a straight man and discovers she is actually bisexual.

Some non-human animal species exhibit bisexual behavior. Examples of mammals that display such behavior include the bonobo (formerly known as the pygmy chimpanzee), orca, and the bottlenose dolphin. Examples of birds include some species of gulls and Humboldt penguins. Other examples of bisexual behavior occur among fish and flatworms.
Pansexuality is also sometimes included under the definition of bisexuality, since pansexuality rejects the gender binary and encompasses romantic or sexual attractions to all gender identities.
In some contexts, the term pansexuality is used interchangeably with bisexuality, which refers to attraction to individuals of both sexes... Those who identify as bisexual feel that gender, biological sex, and sexual orientation should not be a focal point in potential relationships.
The reason some individuals develop a gay sexual identity has not been definitively established – nor do we yet understand the development of heterosexuality. The American Psychological Association (APA) takes the position that a variety of factors impact a person's sexuality. The most recent literature from the APA says that sexual orientation is not a choice that can be changed at will, and that sexual orientation is most likely the result of a complex interaction of environmental, cognitive and biological factors...is shaped at an early age...[and evidence suggests] biological, including genetic or inborn hormonal factors, play a significant role in a person's sexuality (American Psychological Association 2010).
No conclusive evidence supports any one specific cause of homosexuality; however, most researchers agree that biological and social factors influence the development of sexual orientation.
Most health and mental health organizations do not view sexual orientation as a 'choice.'
Sexual orientation identity—not sexual orientation—appears to change via psychotherapy, support groups, and life events.
