When bisexuality has become visible, it has often been within a framework of common cultural understandings which serve to discredit it. This has sometimes been to the extent of dismissing bisexuality entirely, which therefore makes it invisible once again. The term biphobia is believed to have been first used by Kathleen Bennett to refer to “the denigration of bisexuality” as a valid identity. Bisexuality has sometimes been understood as purely a performance by sexually adventurous women to seek the attention of heterosexual men by kissing other women. Biphobia, bisexual negativity, and bisexual marginalisation are nuanced according to a range of factors. Researchers have frequently reported that bisexual people experience double discrimination, but recent research indicates that heterosexual people are sometimes more negative about bisexuality than lesbian and gay people.
