Sex felt amazing for husband, but painful for me


Usually I REALLY love sex, but this time it was extremely painful. We didn't use an abnormal position or anything. The deeper my husband would go, the more it would hurt.. so much that it didn't feel good at all. On the other hand my husband said that I felt the best I ever have, and it felt amazing for him. Also, I am not having slight tailbone pain now. Has anyone else had an issue with this? This has never happened to me, and I don't know what to do..
