I've only seen a few seconds by mistake (internet popups) (enough time for me to shut it off), but there has never been, nor will there ever be a time that I actually watch it. The only "gay porn" I'll ever watch is when it's 2 women. No fuckin' way I'm ever willingly watching two dudes going at it.
I downloaded mislabeled porn once and ended up with guys sucking each other off.
I watched a couple seconds, scanned it and determined I wasn't gay due to my complete lack of a boner.
It's not gay to look, it's gay to get off on it. But I find man on man sex to be something I'm totally not interested in, so I don't watch it. But that goes for gay porn, Woody Allen movies, sitcoms, all of it. If I'm not interested in something I just don't watch it.
