Started cutting due to my male circumcion, now I don’t know what to do

So, during infancy my parents had me circumcised. Of course, this was done without any consent from my side or medical reasoning. And they never told me what was they had done to my body. I always felt that something is wrong, but went into detail only after maturity during my teen years. This made me straight up hate my body, it felt like an instinct or something. Firstly, I started purposely cutting my genital area, because if my parents wanted it to be mutiliated, I'd rather have it more or less destroyed. It's like a way of revenge or something. After there was almost no spots without scars, I switched to other body parts.

And now I have a problem, that I don't have anywhere good to cut, without causing unbereable pain, but the urge to do so doesn't go away. Do you have any suggestions how to stop? That would be the main priority, at the moment. Later, I'd think of other, not so harsh ways, on how to continue teaching my body and my parents a lesson on what they did to me.
