The following outline is provided as an overview of and topical guide to human sexuality:
Human sexuality is the capacity to have erotic experiences and responses.[1] Human sexuality can also refer to the way one person is sexually attracted to another person of the opposite sex (heterosexuality), the same sex (homosexuality), or having both tendencies (bisexuality). The lack of sexual attraction is referred to as asexuality.[2] Human sexuality impacts cultural, political, legal and philosophical aspects of life, as well as being widely connected to issues of morality, ethics, theology, spirituality, or religion. It is not, however, directly tied to gender.[citation needed]
Oral masturbation – stimulation of one's own genitalia by using the mouth, lips, tongue, or teeth (only possible for flexible people or contortionists).
Autofellatio – oral stimulation of one's own penis.
Fisting – insertion of a hand into the vagina or rectum.
Footjob – stimulating another person's genitals with the feet.
Group sex – sexual activity with more than two people.
Irrumatio – when the penis is thrust into someone else's mouth; in contrast to fellatio, where the penis is being actively orally excited by a fellator.
Sumata – type of stimulation of male genitals popular in Japanese brothels: the woman rubs the man's penis with her thighs and labia majora.
Vanilla sex – sexual activity that is considered normal by society.
Sexology – scientific study of human sexuality, including human sexual interests, behavior, and function. The term does not generally refer to the non-scientific study of sex, such as political analysis or social criticism.[3][4]
