Me and my bf had sex on the last day of my periods.we both had dry sex.he moved his erect shaft outside of my vaginal area..he weared an underwear+trouser+jeans and i had underwear+leggings..after sometime his jeans got a bit wet...accidently he touched those wet part from outside of hiss jeans and with that finger he touched my vagina by putting inside my underwear.Is there any chance of getting pregnant??
