I'm probably going to get a lot of hate mail for this, but I really dislike how everyone tries to jump to the conclusion that if you play with other males that means you are gay or bi. Ever stop to consider that the turn on might be due to the fact that the attraction is to the taboo in itself which causes the sexual arousal. So many people on here sound like homosexual recruiters and are very biased.
So in my opinion, what you're doing just means you are really fucking horny, and like playing on the edge a little because it turns you on that what you're doing is wrong. In the end, do what you want, and don't give a crap what many of the recruiters say.
