In discussions of sexual orientation the term is chiefly used in contrast to bisexuality and other non-monosexual orientations, such as pansexuality. It is sometimes considered derogatory by the people to whom it is applied.
The Kinsey Reports found that, in terms of experiences leading to orgasm, 63% of men and 87% of women could be described as "exclusively homosexual" or "exclusively heterosexual".
The term monosexuality has also been used in contrast to polysexuality, where that term is used to refer to people who desire or fantasize about sexual relations with more than one partner. Under this definition, a monosexual person desires sexual relations with only one partner and (like polysexual people) may be homosexual, bisexual, or heterosexual.
