basically last week i was fingering my girlfriend but before that i went to the bathroom and touch my penis with both hands and im almost sure i had precum on it but then i washed it just with water and then i dried my hands but not too much, after that i inserted my finger like 1 cm in her vagina, she was in her most fertil days 15 after her period, so my question is can she be possibly be pregnant? and can sperms live after they touch water or how long can the live in the outside??
relax, getting pregnant with precum during intercourse is uncommon, so even if you knew it was for sure on your finger, the chances would still be slim. and the fact that you wet them and dried makes it impossible. so relax and forget about it. but if you are going to continue to fool around a possibly have sex, then she should probably be on birth control.
good luck and take care
