I've never had sex but my boyfriend fingers me. Can you get pregnant from fingering?
Fingering on its own can't lead to pregnancy. But it is possible to get pregnant if a guy gets pre-ejaculate (precum) or ejaculate on his finger and then puts it in a girl's vagina. The chances of this happening are low, though.
A more likely situation than pregnancy is getting an infection from fingering. So not only will you need to avoid any contact with precum or ejaculate, your boyfriend should wash his hands first and you should make sure neither of you has cuts and sores.
If you have any questions or concerns, or if you think you might have an infection, talk to your doctor.
