Are you on any medications? I've gotten better partly because of various meds (Anafranil and Xanax are the most effective ones for me), but also because of resisting washing my hands when something minor happens (I'm still not able to resist if I bump or touch a "bad" area). It does get easier once you've gotten over the hump of anxiety that you have to deal with. (The meds help with the anxiety.)

I understand if you aren't on meds and don't want to go on them. I'm just saying they helped me, but there are side effects I don't like, too.

Can you put lotion on your hands? If that isn't a problem for your OCD, I suggest a good moisturizing lotion. I use Curel Ultra Healing Intensive Lotion for Extra-Dry Skin. If your skin is cracked, it will sting at first, but as your skin heals, it'll stop.

Hope you get to go to your prom! I know you're nervous, but try to focus on the fun you'll have.
