I agree with buhl, above. There's nothing wrong with you, it really just isn't for everyone.

My wife and I talked about this before marrying and decided we would never have children. Too much time, money, worry, etc ... We are not willing to trade the freedom we have without kids for the joys (apparently having kids is joyful, lol) of having them.

I can't say that I don't like kids, though. Some of them can be bratty, others can be cute as hell, and surprise you with their insightfulness (I teach) .. But yeah, not for me, thanks =)
