I'm gonna get shot for this, but...
If you continue to watch gay porn, and are continuously curious about homosexuality, maybe you might have some bisexuality about yourself, but it is your own guilt and shame that brings on the disgust?
Story - I used to work in a gay bath-house (Oh, the stories I could tell!), and there was this one guy who came in very regularly. He would come in, looking to the floor as he was paying his cover, barely speaking, obviously ashamed of what he was doing. Rush into the changing rooms and head off into the venue, already hard. After 30 mins, there was always a commotion upstairs, and he would come hammering down the stairs shouting "Fuckin queers!" or something of the same effect. Get dressed, banging and slamming around, and being quite violent. If someone would stand up to him, there would be a fist fight. And on his exit he would say, as he passed the counter, "You should fuckin bar me from this place, its full of fuckin faggots!" After a while we got used to him and when we heard him coming, we held the door open for a swifter exit. lol
Obviously, when he shot his load, and the horniness passed, his guilt and his own shame kicked in with a vengeance, and he couldnt handle it.
Reason for the story? Be honest with yourself! You dont need to post a reply to prove anything.
Incidentally, Im a gay man, who gets grossed out by gay porn. There are only a very few (like one or two) gay pornos i have seen that I liked. I much prefer straight porn.
