The thing about the pill is that some women are crazy and will lie about it or will stop taking it in order to get pregnant. And I'm terrified of that happening.
So I use condoms. Work fine for me. I have used withdrawal before, but only because I was young and reckless.
But, hopefully soon, there will be a new type of birth control that requires an injection into men, a one-time injection that will last for years and years and is reversible and is, barring a case of mis-application, completely effective thus far.

RISUG is its name, and will definitely put birth control out of business. It's freaking awesome.
This way, there is no way for one member to lie to the other member in order to cause pregnancy. No chance of poked condoms or purposefully skipping birth control. Nothing. And I'm fucking excited.
Edit: I seriously got ninja'd? Well that's good, means that knowledge of this awesome, awesome procedure is spreading quickly.
