I too, had dated a woman who had a child at such an early age that they would both frequent the nightclub scene together!
She always told me she had a daughter, but I never knew how old until I was at her place once, and a girl who had a striking resemblance (I thought was her roomate) walked in. That was pretty wierd.
But considering their lifestyle, I don't think the "stepfather" issues would have even come into play.
Needless to say, I had a very casual relationship...
