I'm afraid I have to agree with Oz - you're probably in the wrong forum. You mentioned in your title that there was child abuse, but the only thing I see here is a friend getting a little too friendly in the 7th grade. At that age it seems to me you're old enough to say no to someone your same age. In my limited experience, I think most guys like to have their penis touched, so I don't think that makes you gay. Have you ever had the same experience with a female? If not, you don't have anything to compare against.
If you're trying to boost the testosterone, there are lots of male formulas out there with gensing, saw palmetto and other herbs that are pretty specific. If you're trying to come out of the closet, then this is probably not the place to get it out there. As far as the Muslim religion goes, I don't know enough about it to be qualified to advise - sorry.
