a buddy from a few years back.. str8 guy.. was horny.. and missed his girlfriend. We had been away from home for 3 weeks. I sucked him, but he never shot. He said it felt good. But he seldom cums from a BJ. .
Another roomy of mine.. The guy was a asshole, hinted to me to suck his dick. but I didn't do it.
I dont feel that just because a guy has another guy suck his dick, don't make him less str8. just courious. . Just because you try something once, dont make you that way.
But yes.. depending on the guy.. and dick.. I would do it againl
