No sex in a relationship

I started an exciting new relationship two months ago. In the beginning, the sex was frequent and really good. Now, my boyfriend barely ever wants to have sex, and when we do, it is very simple, quick and unenthusiastic on his part. I am fit, healthy, sexually centered and he tells me, sexy. When I make gentle play advances, he always says that we will do it later, which does not happen. What to do?? It's too early in a relationship for the mundane to settle in... help!!

Iv had the same problem with previous boyfriends. I have been honest and upfront, if they cant satisfy me sexually im sorry but it just wont work. If sex is a big part of a relationship for you I would put my foot down now before it becomes even less frequent.
