Finally had sex!

My hoyfreind and i have been together for a year. We are both over 20 years old. Since September we had tried having sex but every time it will hurt me severely. I was worried I will never be able to feel him inside of me. I recently got on birth control to. He came over Friday and left today, Sunday morning. We been having sex the whole weekend.

But I was only able to take it from the back. It still hurts me when we try missionary.

Any advice?
