Well, for one, pleanty of research has confirmed that female sexuality is more fluid than male sexuality, and that’s okay. Secondly, speaking as a bisexual woman, it’s definitely a harsher world for bisexual men to live in — and that’s saying a lot. Bisexuals, period, face a lot of prejudice from both gay and straight people who assume they know our preferences and identities better than we do. But bisexual men are seen as either creeps, freaks, or gay men who are too afraid to come out. If the stigma weren’t there I think we’d have a lot more openly bisexual men on okcupid.
