Help with my Homosexual-OCD!?

I wouldn't worry about it that much. I think you are bordering on hypochondria when you show how much thought you have put into having a problem. It shows signs to me that your more worried about having some kind of disorder than you are of actually being gay. As far as the being afraid of being gay that is normal because it is a cultural norm to be afraid of something different. My advice would be to try to go out with a girl, dispite how your attraction might waiver. See if that can clear your mind, but mainly just give it time. You are 15 and in your sexual peak, you are thinking about a lot of things wether you want to or not.
