see after my ejaculation, i wiped what i think most of it. with a handky. then i put my boxers back we talked and talked after a while we were playing again. and then i rubbed my penis with her vagina for almost 10 seconds. my dilemma is that, what if there's some left over sperm in my penis will she get pregnant? 

 

ps. it was freaking hot there. i don't know if it will contribute. but they said sperms can't live in hostile environment so maybe the sweat of my penis kills 'em? help please
