 Despite being bisexual in fantasy and activity, these men identify as "gay" or "straight" rather than as bisexual.This erasure of bisexuality is sometimes caused by denying the significance of an erotic encounter in order to maintain a person's sexual identity and sense of community; a man might downplay having had sexual fantasies or encounters with a woman in order to maintain his identity as a "gay man" and his membership in the gay community, or a man might downplay having had sexual fantasies or encounters with a man in order to maintain his status as a heterosexual man in heteronormative society.Writing for Bisexual.org, author and columnist Zachary Zane cites a study showing that 20.7% of straight-identified men watched gay pornography and 7.5% reported having sex with a man in the past six months, while 55% of gay-identified men had watched heterosexual pornography and 0.7% reported having sex with a woman in the past six months.
