ur putin us on meby? Or, if you're serious (apologies), take Nick's advice or decide that you're actually hetero and go for hair pie instead. If that doesn't work either, become celibate or go to a shrink. If neither of those works...... Good luck in sorting it out.
My personal opinion, I think you aren't comfortable with homosexual actions. I maybe biased since I'm gay, but I think sexuality is fluid. Do what you want. If it's not what you feel at the time, just don't do it.
Hey man I know exactly what u mean when I'm hot and bothered I want a cock but when I'm not horny at all I don't EVER think of it. I've never really been with another guy though so I don't know what I would do if I was in that situation.
