Like most bisexual men, I found it easier to stay in the closet. Not that I was happy there by any stretch of the imagination, but I found it easier to fake being straight since I was attracted to women. I experienced a lot of the same fears many bisexual men have about coming out. And homosexual men would view you as a confused child who hadn't made up his mind yet. So, like most bisexual men, I buried the side of myself that was attracted to men, and lived as if I was straight.
Bisexual women face the plague of biphobia too.
After coming out bi, they are rejected by lesbians who can be less accepting of bisexuality than gay men. Then their male partners expect them to fulfill the menage a trois fantasy, which turns bisexuality into a degrading porno. So many bisexual women live as straight. Some bisexuals become homosexuals giving into pressure from their friends who insist that they are really gay. And often they sweep away their attractions to the opposite sex and call themselves homosexuals.
