Oh well too bad, if she does get pregnant she'll hound you for child support payments. mmm at least next time if you sleep with a girl and don't want responsibility...I guess tell it to her face all you wanna do is bang bang bang cause you know girls can't read your mind....and if she still is willing to sleep with you then use a condom. Thats the best advice I can give you.
One thing about the society is that, if you caused it you have to take full responsibility whether you like it or not. Well at least in America, dunno about Europe, Asia, and etc.
ALSO! Think of the children!! You ruined another life, do you know how bad it is for the child to not have a father? Make the mother single and work her ass off just because of an ass like you that caused part of this?!?! Don't think with your penis...
