I am a scalp picker, primarily. I will pick at my scalp for hours. I enjoy making it bleed and I like looking at the scabs.

Anyway, I've been doing this since I was eight years old. It was consistent, non-stop picking up until my early twenties, and since then I just go through phases of it. Right now I'm going through a picking phase again.

I'm not sure what causes the phases of picking. Any thoughts?

I know how to make myself stop. It's just I always enjoy it so much that I never want to stop until it becomes so time-consuming that I don't really enjoy it anymore.
