He Doesn't Want to Have Sex Anymore: How Can I Change His Mind?

cupcakewars77 asks:

My boyfriend for about two years now told me he doesn't feel like having sex. I told him I still do. He says all we ever do is have sex. That's not true. It's frustrating but I want sex and he doesn't. He is going to college this year and I won't see him as much because he will be so far way. Whenever we are to "fool around" he gets all serous and say I don't feel like having sex or no it doesn't feel right even though I am on the pill and we always use perfection. Always. Am I doing something wrong? Is there a way to even get him to have sex with me? I am confused and stressed out. It's been months and I feel like he is pulling away. Help!
