That's because it is wrong and if you do it you're a whore and a slut. Just because you're gay doesn't mean you get a free pass to do all the degenerate shit girls do without facing the same shame they do.
Fucking disloyal faggots all over this board. Tons of people in relationships but posting nude pictures of themselves like they're desperate camwhores, people hooking up with strangers every week, people talking about being so disgusted with the 40 year old fat hairy man they met on craigslist but so desperate for cock that they sucked it anyways.
Nobody respects that kind of behavior when women do it. Nobody respects that kind of behavior when men do it.
