HelloI'm sorry if this is a stupid question but something's been bothering me for a week. Here's what happened: I went to the toilet in a store right after making out with my gf, I had a bit of precum but took care of not smearing any on my fingers. I was in a hurry so I didn't wash my hands after urinating. Just a few seconds later, I paid for a purchase with my credit card, which I handed to the female cashier. Now, I'm agonizing that I might have put precum on the card, and therefore maybe on the cashier's fingers, and that she might get pregnant from that (for instance by masturbating). I've read that precum does not contain sperm if there was no full-fledged ejaculation earlier (none in my case, as far as I can remember), and that urine kills sperm. Is there really a risk of that woman possibly getting pregnant because of this? I know it sounds silly but I feel like I'm going crazy. Thanks for any help.
