I'm not sure how much I should say.
Yes it hurts but it feels good to me. I cut. It is dangerous. I've never had to get stitches. It numbss my emotional pain.
Now for my advice. Don't try it. I found it extremely adictive and want to stop but can't get myself to. It hurts myself emotionaly and others that I really care for. I wish I had never started. It dulls the pain temporarily but only increases it later. Please don't try it.
