I had this problem when we were first married which put a real damper on our honeymoon!! Luckily for me I was able to have it removed surgically as it was only one small area. My gynie said it was on an ovary in the worst place for pain but the best place for being able to fix it.

So even though I only suffered with it for a short time I can totally sympathise with the feeling, and it did take me a while afterwards to enjoy sex again as I was always tense in anticipation of it maybe hurting again.

I hope you can find a solution.
