Can you get pregnant from pre-ejaculated fluid on your hand if you only touch yourself through toilet paper while wiping in the bathroom?

Pre-ejaculate can contain some sperm. Sperm can live for a short amount of time outside the body. Wiping after urination could transfer some sperm from the hand to the vagina. Sperm can travel all the way up the vagina.

It's safest to wash one's hands after a hand job.
