I am seeing this man , and just recently we started having sex, and after every time he cums inside me my vagina burns, no it does not itch, nor swell, nor hurt when I pee. Just burns on the inside. No, I am not taking any birth control, he is fixed and can t have children. I am 20 years old and never have never had a man cum inside me, so he is the first, and I have only had sex with three males including him. What s going on ?
