no she wont get pregnant. the vagina is full of toxic chemicals to kill of bacteria and even semen. about 70% semen from a full ejaculation is killed from the natural toxic chemicals created by the female reproductive system even before it reaches the uterus. so if i were you i wouldn't stress out too much about your girlfriend getting pregnant cause the chances of your semen reaching an egg is about a 1/10000 chance.
could my girlfriend get pregnant if the small amount of semen i had on my hand made contact with the vulva? . me an my girlfriend were performing manual sex and as we are youngish we have decided this is all we would do she performed a handjob on me and i cummed and then about 3 minutes after i rubbed her clitorus and vulva with my hand which (from what i remember) contained a slight bit of semen do i have a risk of pregnancy? she was not on her period or in the stages of ovulation.
