just a couple more things - what was the 'dumb wild stuff' that your first friend got you to stop doing, and when you say that you acted on your feelings and that now he hates you is that because what you did was bad or because he thinks that you must be a pedo?
are you normally attracted to women and have you had sex with anyone your own age?
sorry about all the questions and dont answer them if you feel its too personal . . .
going from what you've said already it could be that what you really liked was the fact that the boy took you seriously and needed you. He looked up to you and we all need that so much, especially if it doesnt happen often. I know that is how it was for me. Children are so trusting and its good to be trusted . . . . so that could be it . . . .
if you arent attracted to women then it's going to be a bit harder. Either way, the main thing is to try to make friends with guys and girls your own age so you dont get yourself into really deep s***
