Can I get someone pregnant if I have semen (cum) on my finger and touch her vagina?

if i had cum on my finger ang fingered a girl could i get her pregnant?

Yup. If fresh semen (cum) gets in someone’s vagina pregnancy is possible, no matter how the semen got there.

Most of the time, pregnancy is caused by vaginal sex, when a penis ejaculates (cums) in a vagina. But fingering can also cause pregnancy IF there’s semen on the hand that’s touching the vulva. So if you’ve got semen on your hands, wash them before touching a vulva or vagina to prevent pregnancy.
