Hi there everyone. I decided to make this my very first post because it's the subject that I don't talk about. Ever. I'm well aware that everyone here has a problem much larger than mine could ever be, but I need to ask this question in a place where people won't think I'm off my rocker.

Here goes: Are there any biters out there, people who injure themselves not though cutting, burning, pricking, etc., but those who bite themselves hard enough to leave bruises/scarring/wounds? Does anyone know of anyone who does this or have any information that they could give me?
