you lucky s*d.
first things first is that don't try to keep your sexual urges down. go and have fun. don't listen to dreadful people who tell you you should hate yourself for having a good time. the notion that our biological impulses are sinful is a source of alot of neurosis. However, at the same time the belief that these urges are sinful can debase the experience and mean we pursue shallow sexual relationships over deeper and emotionally fulfilling ones. By that I don't mean the bordem and frustrating of monogamy, as fulfillment is about following your emotions rather than social norms AND not getting hurt. thats my onlyn qualification to be honest. sex isn't a purely physical relationship but is a psychological one as the passion involved is supposed to produce a strong bond- that doesn't mean it lasts forever but is just good while it lasts.
if you think it is a problem, I'd suggest reading Wilhelm Reich's
The Sexual Revolution. this is only if a) you end up in exclusively casual relationships and are unable to have deeper relationships with people or b) you consistently end up in relationships where you or your partner get hurt. thats when I'd say your in trouble. its the book which is pretty much THE source for ideas on sexual liberation but was written specifically intended for his times. the first half of the book may give some pause for thought as it discusses alot of things quite openly. I'm bi and have had to go through alot of stuff to figure out my sexuality as I was very inhibited. I'm pretty sure that sex isn't the problem, the sense that sex is a form of debasement will be.
but what ever you do. don't listen to god. go sin and be happy. life is short.
