undrdg, I'm seconding newmama's advice to try a 12-step program for sex addiction. If you truly want to stop this behavior, you can get help and understanding.
From what I've read, it does seem to me like an addiction and a difficult problem to solve on your own. You'll need a support group that understands and can help you recover.
Good luck.
