Homosexuals are attracted to other people of the same sex: women are attracted to women (lesbian) and men are attracted to men (gay). Homosexuality is often seen as the opposite of heterosexuality: you are either homo or hetero. Indeed there are many other sexual orientations between heterosexuality and homosexuality, which were once all subsumed by the term bisexuality. Homosexuality can be a general tendency, but may also occur situationally.
