My boyfriend and I have been together for about 8 months, and up until a few months ago, our sex life was going strong, and everything was great, and the last few months, the last thing I want to do is have sex. I think it started when sex started to become painful, but I quickly attributed this to the ribbed condoms he had been using. But then about a month or so ago, we were having sex, and after about 10 minutes or so, I started screaming and sobbing and had to push him off of me because I was in such intense pain. It felt like there was extreme pressure on my pelvic area and the best was to describe it would be that it felt like my uterus was "full". It hurt to even breathe deeply. I thought I was going to have to go to the hospital. The pain lasted for over an hour until I fell asleep. Pretty much ever since then I have been avoiding sex. We have sex probably once a week now, and I pretty much only do it as a favor to him. I don't even want him touching me sexually

, and I don't want to touch him that way either. I know that this must be making him feel awful. I just can't seem to get aroused anymore and don't look forward to sex at all. It hasn't been painful at all lately, so why do I still not want to do it? Little help please?
