I'm ashamed of my kinks

I'm 16 and I have these disgusting fetishes. I have one about wedgies, one about enf, and one about rape (the last one isn't very intense). I only fantasize about characters from TV shows; I don't like to involve real people. I've always been ashamed of this part of myself. Last year I tried to quit, but I relapsed, and it disgusts me to think that I might hurt someone or myself with these desires. I'm afraid to go out and hurt someone. I've been clean for five months now, but I'm terrified of going back to it. I know fetishes can't be eliminated, but at least I want to control them.
