OK, this is odd ... I was having oral sex with a guy I met last night; everything was fine until suddenly he bit down - HARD - on my penis, twice: once just below the head and once towards the base. I shoved him off, because it sure as hell did not feel good, and we were more or less done from that point (understandably!) ... later, I go to urinate, and the pain was awful - I figured it was due to the bite, but I didn't notice any blood or anything. This morning, I go to masturbate, and more than a few drops of very dark red blood came from the tip. This made me panicky. I then had to urinate, and again it hurt like hell but no blood. I'm pretty sure it has to do with the biting, but what is there I can do? Will it heal up by itself?
