text: Well if u used a condom, u might be allergic to it.\nAnd if you didn't and she was a virgin, she may have been a little tight for you and caused irratation. Make sure to wash after you do it and WEAR a condom if you didnt.\nIf she wasn't a virgin, maybe she has something and might have given it to you. You may want to see a doctor and get tested, and have her tested too.
