Hi. Im 18 years old and im very curious about this. I have a small bump right below my pee hole. I believe its called urethra. I can feel the bump if i reach down and touch the opening of my vagina. It is right inside of my urethra and its about the size of a pea. It hurts when i touch it and it hurts when i have sex. I feel the pain when my boyfriends penis pushes against that area which is basically the whole time we are having sex. I can also feel it and it hurts when i sit down sometimes. The moment i sit down i put pressure on it and it hurts. I doesnt hurt or bother me when i pee. It onpy hurts when it is touched. Some additional information; It cant be an std because i have only had one partner and we lost our virginity to each other. We have been together for four years. I have also been tested for std's like about 6 months ago when i went to get a birth control shot. I tested negative for evrything and the nurse said i was good. I stop using the shot for birth control because it made me gain about 25 pounds. I didnt like the side effect so i didnt go back for anotherone. We use condoms sometimes but it cant be an alergic reaction because i have never had a problem with condoms. And im not alergic to anything. And by the way, this is the seconnd time its happened to me. both times this year. The first time i had the same symptoms but then it went away within a couple of weeks. It has come back now and im very concerned. please please please! What could it be? I reallyappreciate any information!
