admitting a nasty problem

hello everyone, im new here, and actually just figuring out about dermatillomania. for years now i've been picking at the skin on my "private area". weird, but i cant help it. everytime i go into the bathroom it ends up happening. its only getting worse too. its strange, disgusting, and hurts quite a bit. i really dont want to do it but the urges have kept me subdued this whole time, i really cat stop. i have NEVER spoke about this to ANYONE. if anyone has any type of advice at all, il gladly listen, and if not it still feels great to open up about this.
