I have to agree with edward here. Having sex is a choice, but it seems having a kid is not your choice. It's truly out of your hands unless you use a condom and pull out or some other way. All in all it's just the luck of the draw if your girl gets preggers or not. Speaking of which my fingers are crossed this month.

EDIT: One of my friends just got his girlfriend knocked up using condoms and the pill. God hates him.
