Ok, a couple of years ago, me and a friend(who was my age) were masturbating together, and comparing and stuff. Anyway, he had slight learning difficulties(he couldnt write. I now fear I would do it gaain if I were in the same situation, but I can't imagine doing this kind of thing with someone who is more intelligent than me, or who is my age now. I have now got it into my head that I take advantage of people who are 'vunerable'(couldn't think of a better word). I'm starting to get depressed about it. Does anyone know what I can do to stop this?
