I'm in the same boat, GS. I found a picture of me when I was 6-years-old this weekend, and that though crossed my mind. My father was married and had a kid (me!) by the time I was his age. He was actually working on his second marriage!
I feel like I'm still growing up. I don't know if I'd want a real relationship considering how much I travel nowadays (I was just in Delaware, when you blink I'll be in Illinois, Los Angeles after that, etc.). Women tend to not be very good about that type of stuff.
