that's exactly where I am right now. I have this buddy of mine that is married and have a kid, he's so fucking 'hot', manly and yet a bit in touch with his feminine side... a womanizer and let's just say plain HOT.
We went to a ski trip where I pretended to be asleep and ended up leaning my head on his shoulder while my left knee was on top of his right knee... what a jolt of excitement that was. But at the end of it, he didn't do anything more than the ordinary, he's jusy freaking straight
we still go out for lunch and go for a beer once in a while, but that's just buddies hanging out kind of thing.
So, to cut it short, do some sexual move on him and see the kind of reaction he'll give you, who knows you might get lucky and hit the jackpot.
