How do I go about this?

Me and my boyfriend have been together for almost two years. on Valentine's Day we had sex. It was his first time and I had already had sex but by different circumstances. Now it seems this is what he wants all the time. Now before we all go off on a spew about sex and being young I sat down with him and talked with him and I had him talk to. He agrees that we shouldn't continue but I need advice anything helps with the situation. Thank you
