Actually, this isn't a matter of biology, but a matter of human interaction. You see, while it does take a man and a woman to make a baby, the sole determining factor in whether sex occurs is the woman. With the exception of rape, no man is having sex no matter how much he wants to unless the woman allows it. She is in control of the situation. Remember, it is you left wingers who claim that women want to control their own bodies and make their own reproductive choices. Well, it seems to me they only want to make those choices AFTER an innocent baby was conceived.
As I say, abstinence is 100% effective. It works every time it is tried.
To me it is a matter of simple common sense, which judging by these conversations, it would appear that women don't have.
If you don't want to get addicted to heroin, you don't try heroin. If you don't want to get addicted to cocaine you don't try cocaine. If you don't want to die in a terrorist attack, you don't climb on a plane filled with OWEblahblah's new buddies the Muslime Brotherhood. And, drum roll please if you really don't want to get pregnant, don't engage in the behavior that leads to getting pregnant.
Why is that so hard for libtardiots to understand?
