Me and my boyfriend are having problems during sex; Help?

When you are doing the work he can just sit back and relax, knowing that you are satisfied because you wouldn't be doing something you dont like... When he is doing the work he is most likely worried about how you feel and if its good and trying not to finish to soon. If im right, he is just worrying to much, try making it known when he is doing the work, that it feels good, try moaning or saying how good it feels.
