We all know that there is a fine line between pleasure and pain, but I think that my friend is crossing that line. She revealed to me that whenever she masturbates, when she's having an orgasm, she will take a razor blade and cut herself. She showed me on her hips where she is doing this and it really freaked me out. They aren't just little scratches. Some of them really needed stiches. I don't know how to handle this or what to do to get her to stop. I know that being a masachist is okay, but she is taking this way to far. Please Help!!!
