Can someone be CURED of OCD?

When I was about 11, I used to wash my hands every five minutes and constantly smother them in germ-x. Over time, I got better and better, and after I was like 14 or so, I stopped caring about germs. I actually have VERY low regard for hygene now. I will kiss frogs, scratch my (with my hand inside my undies), and do very gross and nasty things and not even wash my hands afterwards. I've gone from a neat-freak to a swine.
