Boyfriend is Christian, I'm not.

I converted to atheism a while back and my boyfriend is totally cool with it. What's funny is 50% of the time we have the EXACT same views. But the other 50% we don't. He is very much into abstinence but I'm not so it's a little annoying. He's a great kisser but I don't want to go through college without it! I love him and I'll never leave him but it's annoying. How do y'all deal with urges? We do sext a lot so that's fun but still.
