I normally lurk almost exclusively, but I feel somewhat compelled to but in this thread.
I had known my best friend as a kid since I was about five. We always stayed over at each others' houses and slept in the same bed. Our parents would let us take bubble baths together. Early on, there wasnt anything explicitly sexual about it, but I remember always getting boners in the bath and poking each other (and popping it out of the bubbles and pretending it was a submarine
)
Around twelve, we started fondling each other in bed, though we didnt jack each other off at that age. By junior high, we were giving each other blow jobs. We tried anal sex a couple times, but it always hurt me too much, probably because we never had any proper lube.
We rarely hang out anymore, and havent talked about sex, but I think we'd both be willing to try it again. I have no interest in the gay lifestyle (though I completely support gays) but I'm definitely interested in the sex end of it.
