I got with my wife when I was 17 and she was 16; the only girl I've ever been with. She has turned out to be one hell of a woman, and I can't think of any chick her age that could even come close. Sure, sometimes I wish I'd gotten around the block a little before I settled down, but what I have now is more important.
I look at the friends I grew up with who are now ready to settle down, some have great jobs and would make good husbands and fathers. Their outlook on finding a good woman is bleak, as most the good girls are already taken. And when my friends look at me, they are jealous as hell.
