So the other day I was fingering my girlfriend and I was using my hand that had not come into contact with any pre-ejaculate, however my other hand had and I may have accidentally touched (but not fingered) with dried precum on my hand. I read that pre- does not contain sperm, and I know that I had gone to the bathroom at least once and maybe twice beforehand cleaning out my urethra. Do I have anything to worry about?

Precum DOES contain sperm.

"Cleaning out my urethra" by urinating DOES NOT necessarily remove all sperm.

You are engaging in risky behavior. If you don't want to be called "Daddy" in about nine months, keep your pants on and zipped.

Yes, while harder and less likely, she could get pregnant from that.

Precum does have sperm in it, and urination does not get rid of sperm.

Sorry now she and you wait to see if the next period comes or not.

Odds are she isn't pregnant.
