Removing silicone lube?

I used some for the first time ever in the shower today. And it was great, but I'm not sure how to get it off me because it's waterproof. Is it okay to just leave it? I'm sure it would come off by itself eventually. But if it could cause issues to my junk, I'd rather get it off.

Edit: I've already tried washing off with soap and water and it hasn't worked. Thanks anyways..
