ok, so i am a 17 year old girl and have only had 1 boyfriend. and he says he has never had sex before; we havnt had sex, but he has touched my vaginal area with his hands and i have touched his penis with my hands. He has also done this to one other girl. That is as far as we have gone, but recently i have noticed a bump inside the skin, by my vagina. It does not hurt or itch. I was wondering what it could possibly be and i dont have anyone to ask. I am very worried it sould me an std or somthing serious. Please help me!
