I was 29 when I got married 24+ years ago. My wife was just 20 and got divorced a few years later. We actually met while she was still married, and waiting for the divorce. I had never been married before, although I did have several long term live in relationships, and numerous short term ones and one night stands.

My wife says that she thinks 25 is just right, you aren't too old to have a child, and you've had the time to play prior to getting married.
