How do I get rid of my sex drive?

I have had a very high sex drive since I was in fifth grade and I am almost 15. I am just tired of my crazy sex drive taking over my time. I feel guilty after it every time and I am trying to stop but I can't. I am Christian and want to remain faithful and wait till after marriage for sex. Some people say masturbation is a sin and others say it isn't. I really don't know, but I do know that the Bible says thinking lustful thoughts is adultery and a sin. I think lustful thoughts while masturbating and I just want to stop. Please don't fill me on information saying why it isn't wrong. Only respond if you have ways for me to try to stop. Even if it natural I want to stop. Any tips?
