can i get pregnant will a virgin

Hi

I think your are trying to explain your boyfriend had his penis in the area of your vagina ejaculating outside of your vaginal entrance, but do you mean he ejaculated within the labia area (inner lips) or were you  both just rubbing against each other with clothing or underwear on?

If you had clothes/underwear on it's unlikely you could become pregnant even if you left them unchanged till you returned home or got to a bathroom.  If however he ejaculated within your vaginal area inside the lips after both of you had been rubbing against each other, there is always the chance some sperm could have dribbled towards the opening and entered.  Any sperm near your vagina can lead to pregnancy I understand in the heat of the moment it's hard to hold back sometimes but you need to think ahead if you have become sexually active, carry some condoms with you and perhaps look at other methods of contraception.

I hope this has helped you<3
