Hello. A few nights ago while fooling around with my girlfriend she let me rub my penis between her legs. I had masturbated and ejaculated a few hours before and wiped any semen on my penis off. The top of my penis may have rubbed up against her vagina. Im wondering what the chances of accidental pregnancy are without an orgasm during or insertion. I know that the only way to guarantee safe sex is to not have it. I m just worried and need my mind to be put at ease.
