I have been using condoms and a lot of lube during sex, but after about 10 minutes I want it to be over. Its not an intense pain, more like a soreness. I am on Nuvaring for birth control and I probably have endometriosis as my Mom had a very severe case, and I have extrememly painful periods. I keep the ring in for four weeks so that I don't get a period (my doctor told me to). I used to like long sex sessions but now I finish quickly and wish that he would too. I should probably go to my doctor but in the past she really didn't give me any useful answers. Anyone experiencing anything like this?
