No. Being a parent is not the life I want, and frankly I would make a terrible one. That's not self deprecation, it's just honest self-analysis - I'm hardly responsible enough to take care of myself, I have personality flaws and neuroses coming out of my ears (including an inability to handle stress), and I didn't like kids even when I was a kid.
I'm very big on the decision to remain child-free being respected - I mean, all life choices that aren't hurting anybody else should be respected, but this one especially. No one should ever have a child that, for any reason, they aren't 100% sure they want, let alone try and convince someone to! It's the most important, and the most permanent decision you will ever make.
...Sometimes, though, I wonder if I'd ever want to be a surrogate mother, just to see what pregnancy is like. That'd be a loooong way down the road, though, so I don't think about it much.
