if my boyfriend fingered me with a little semen on his finger, is there any chance i could become pregnant? im really scared
Yes, there's a chance. However, the chances are very small. There's a reason why a man ejaculates and that's to shoot the semen as far up as it can get in the vagina. There are many antibodies and beneficial bacteria in the vagina that capture "foreigners" and kill them, including sperm. If there was a little semen on his finger, chances are in your favor that the sperm were killed before entering the uterus. I wouldn't worry.
