This brings up an interesting question. Is there such a thing as "gay poly?" I have been thinking about this a lot. Since monogamy is a decision, not a norm in gay male culture, it seems the vocabulary and need isn't the same.
I also don't see any gay men here.
I'm here... lol*waves*
I'm gay. In a relationship with a bisexual man and a bisexual woman. We all three sleep together, occasionally enjoy some sexy times together, all hang out together 3+ times a week. I'm mono. So is she. And he would be if his identity didn't contain dual sides. We are polyfidelitous.
Also, there is another gay triad that posts here sometimes.
I agree that gay men often don't have a use for the language of poly, because non-monogamy is much more accepted than in heterosexual communities, but to assume that no gay men are monogamous is a little ridiculous, whether you know any or not.
