I've been reading posts - on and off - on this thread for a while now: what I can't quite understand is why guys like us would care one way or the other, whether the guy is "straight", "married", or anything else besides needing sex with other men.
At the fuckjoints, I've never heard any guy say something like "I'm straight & married", or anything else even remotely similar. Usually, guys say nothing more than "gimme that cock" or similar - if anything at all.
A guy can call himself "straight", "married", "the man in the moon", or any other qualifier - and it doesn't change anything. Talk is nothing more than that. He's there to either suck cock, get sucked, fuck or get fucked, and that's the only thing that matters. I don't give a hoot whether he calls himself "straight" or any other thing.
He's bent over taking loads, and that's what care about.
