If someone ejaculates outside a girl's vagina and then urinates or cleans it off with water, will there still be sperm left after 10 minutes?
My girlfriend and I had unprotected sex on the 15th day of her 1st period. I ejaculated outside her vagina, and she had a contraception pill(Morning after,Plan B pill) 43 hours later. What are the chances that we could get pregnant?
