I'm 16, and I had a friend of mine sleeping over at my place, (15), and he was saying his back was hurting, so he layed down and I went to crack his back (he told me this is how to do it), and I sat over him with my legs on each side and I noticed I got a b0ner! A full on one and I had to get up and was surprised. I never really knew if I was gay or not becauSe I do like girls and we always talk about girls and who's hot/who's not and have our GF's, but this really worried me. Does this mean I'm gay?
