Dating an early 30's chick for 6 months, she is a fit and attractive 7, very conservative (in a good way), cultured (she is South Asian like I), talented (she sings which I really like), smart, and quite docile. My family loves her, my friends like her, I really like her family and friends. And I actually like spending time with her, talking to her, we have fun together, doing exciting stuff, or just hanging out at home. We are a "perfect match", everybody says so. She would make a fantastic wife, mother, and daughter in law. She definitely wants to marry me, she would do so in New York minute if i asked her. But she's willing to wait another year or so.

Problems: 1. I'm still unsure about marriage, as an institution, and if I ever want to be. I don't think I want to be. 2. I do want kids however 3. After having done it innumerable times already, I'm not sexually attracted to her anymore. I actually have a hard time getting it up with her. This is the big concern.

What do I do? I can't rationalize sexual attraction, if I would I most definitely would with her. I think the chances of my eventually marrying her are low, maybe 20%, maybe lower. And while she would be absolutely crushed if I dump her, what is the point of stringing her along, to eventually dump her anyway? I don't want to waste her time, fertile years, and what is left of her youth.

What do I do?
