Identity conflict or adaptive flexibility? Bisexuality reconsidered.

A definition of bisexuality is offered, followed by a discussion of two opposing models of bisexual functioning: the "conflict model," which views bisexuality as problematic, stemming from identity conflict and confusion that marks a transitional stage to a homosexual orientation; and the "flexibility model," which views bisexuality as the coexistence of heteroeroticism and homoeroticism, as the successful integration of homosexual and heterosexual identities into a dual sexual orientation. The Kinsey data are reviewed in an effort to determine the incidence of bisexuality in the U.S.
