Thanks for posting this - seen it before but still worth another look. All I can say is *OUCH*!!! It looks like he's ruptured his urethra with the way the blood was gushing out.

I had a client that used to do this type of thing to himself. He did it in response to the fact that he was repressing his homosexual urges due to a severely bible thumping mother who controlled every aspect of his life
