My girlfriend and I had sex yesterday, it was her first time, we did use  protection and nothing broke, but she saying shes having lower and middle back pain, My penis is pretty big in girth and length so it was a very tight squeeze,. but any idea why she is hurting?
Hi, This is a traumatic experience, especially if she is not use to having sex, or does not have regular sexual intercourse. If she has spent quite sometime without having sex, or if it were real rough, it might not be necessary to worry. Otherwise, I just suggest you stay calm and watch. Mild painkillers might help for now. Persistence or aggravation, of course rare, should prompt you to see your doctor. Kind regards
