The past couple times I have had sex it has hurt. I thought that maybe I had got scratched. When I looked to see what was going on I noticed a small white bump on my vagina opening. It doesnât burn, itch, sting, have an odor, nor a discharge, not anything. I only feel pain when I have sex. I stopped having sex and I have no pain. I have no idea what this could be. Can anybody help me?
