So somtimes while having sex (I lost my virginity almost a year ago) I have this internal sharp pain when he goes in all the way. It hurts quite bad and once I had to tell him to stop completely. Another time I felt the pain it wasn't as bad and I was able to deal with it, the sex was still pretty pleasurable. The last time I felt pain it hurt quite a lot again so I told him. To stop but I managed to do it a few mins later with no pain. What can this be? It doesn't happen all the time, and I don't think it's bc I'm ovulating, bc the first time it hurt I was on my last day of my period and the other two times at different times during my cycle. (I have a very regular average one since I'm on the pill) but what is this internal pain I feel?
