Was messing around a bit with my partner a while ago and he very gently fingered me. It didn't last long and it really was very gentle. But when I went to the bathroom after I noticed a small bit of blood on the toilet tissue. I had a closer look with a mirror and it doesn't seem to be coming from my vagina but more from the skin in between vagina and anus. Is it possible to have a little cut down there even though he was very gentle, and he bites his nails so he doesn't have any nails at all that could have cut it. It's really freaked me out, and i was doing so well until this.....
