Usually they look like razor blade cuts that run parallel up the arms and on the thighs.
Was just at the car wash and the girl who took my money had about 40-50 cuts on each inner thigh.
All that I've seen lately are Latinas. Don't know if that has anything to do with it, just an observation.
When I was a teen I used cut my arms and do other things to inflict pain on myself. I sort of got a high from it. Almost like I was outside of myself watching it happen. Eventually I ended up sexualizing the pain I felt but it really always was, and still is, a way to get high.
Is that what this is with these girls?
Are boys doing it, too?
