Is it normal for this to have happened?
When me and my wife were first dating, she invited me to her dorm for sex. Once things picked up, I started doing her up the ass. It wasn't until 20 minutes had gone by when I noticed there was blood splattered all over her legs. I pulled out and saw my frenulum had split and was gushing blood. I woke up with stitches hours later having passed out. I never thought something like that could ever happen. But is it normal?
