Bernie, you don't know that you'll never want any. It's like this guy I know who joined the National Guard when he was in his early twenties, while he was single and looking for his lot in life. Now he's married, has a steady and well-paying job, and he wishes to God he'd never joined up because his ass is dangerously close to going overseas.
I remember him telling me I needed to join. I said, "bushwah!" and never gave it a second thought. I say the same thing to everyone who says "vasectomy". It's easier to play war games on a computer or on a paintball course than it is to join the Reserves or whatever...it's easier to just say, "pull out before you blow your load," or "I'm on the rag, go jerk off, sport," than it is to disable your reproductive system when you can't tell what you'll want ten years from now.
