My boyfriend is uncircumcised. He is the only guy I have been with that wasn't circumcised, which isn't a big deal, except for the fact that he tends to have more injuries than any of the other guys. His foreskin tends to pull too far back during sex at times, causing him pain. A few days ago, we were messing around and he started bleeding from his penis- apparently I pulled the foreskin down too hard and caused a slight tear where the frenulum connects to the head. I noticed it was bleeding during a hand job. This is the first time either one of us has experienced this (we are both in our mid-20s) and I wasnt more vigorous than usual. Has anyone experienced this or heard of this before?
