Within both the queer and het communities, bi folk face particular and unique issues. This article lays out the stereotypes and prejudices against bisexual people very nicely. Take a read if you are bi and want to commiserate with some like folks. Definitely read it if you feel bi people are “really gay,” “can’t be trusted,” or can “retreat to the privilege of heterosexuality.”
Oddly enough, as a bi man, I’ve felt some of these things, but one of them I’ve felt in reverse. For many bi men, they are told that because they’ve been with/are interested in men, then they are actually gay and in denial. I got the reverse. Because I have typically been in long-term relationships with women, it would sometimes take work to convince people that yes, I am attracted to men as well. Yes, I do like to suck cock! Not that I ever tried that hard to convince anyone, but still.
