Homosexuality

Homosexuality refers to sexual behavior or attraction between people of the same sex, or to a sexual orientation. The latter refers to a person's enduring identity as disposed to romantic and sexual attractions and relationships with those of the same sex, and not narrowly to their sexual behavior. Homosexuality is contrasted with heterosexuality, bisexuality, asexuality, and pansexuality.

Etymologically, the word homosexual is a Greek and Latin hybrid with homos (often confused with the later Latin meaning of "man", as in homo sapiens) deriving from the Greek word for same, thus connoting sexual acts and affections between members of the same sex, including lesbianism. In the English-speaking world, the term gay had been used within the subculture for decades before becoming popularized by the gay rights movement in the 1970s.[citation needed] In a narrow sense, gay refers to male homosexuality, but it often is used in its broadest sense, especially in media headlines and reports, to refer to homosexuality in general. Lesbian, however, always denotes female homosexuality.

Homosexual behavior occurs among numerous animals other than humans, particularly among social animals.
