without using contraceptives .. LOL !
what i mean is without using contraceptives ..
If you don't want to get pregnent, don't let him do that, Because generally the odds will not be in your favor. Lol.
I would deff not let him come inside you if ur not on some form of birth control because it's always a 50/50 chance u could get preggers!!
if your not trying to get pregnant, your best bet is to get on some form of birth control. usually when your NOT trying, thats when it happens lol
