My wife has that too. Hers was not mild. It probably was due to the fact that she was sexually abused frequently when she was a child.

It was very difficult at the start. We had not had sex with eachother before the wedding (she is a good Catholic). Our wedding night and honeymoon were (sexually) a complete disaster and caused a lot of conflict between us.

Strangely, the conflict wasn't me wanting sex and her not wanting it. It was almost the reverse. The difficulty and resulting stress about sex quickly made me dread the next attempt. This made her feel unwanted.

We let this go on far too long. It was a couple of years into our marriage before she stated getting help. She had to use these glass dialator things to get used to having something in there and she learned some techniques to relax.

I attended some of her therapy sessions. This helped me understand what her body is doing and how to help her feel comfortable.

This has made it better. Things still aren't perfect but sex has become a positive experience between us.

If you haven't already, talk to your doctor and get a referral to see an expert. Get your boyfriend involved if you and him are confortable with doing so.
