Sex hurts! Please please help me!! :(

An
So I lost my virginity last month and since then my bf and I have had sex roughly 15-20 times. It hurt like hell the first time and slowly got better to where I had little to no pain, but still no pleasure. My bf was out of town for a week for work and we had sex today when he got back. I thought it would feel better. But it hurt so bad!!! Almost as bad as the first time! I'm so disappointed, I feel like we are back at square one :( We do a ton of foreplay (sometimes up to an hour long) use lube, use lubricated condoms, tried different positions, different speeds and nothing seems to work. He feels good and says I don't feel super tight, he is about 7 inches and always feels pleasure during sex together but I dont! Please please help me!!! I don't know what to do! He is trying so hard to come up with solutions to help but we are both confused! What could be the problem?
