I am not a Woman but....

I agree with "wanttoescape". It has more to do with the person and more so the experiences they have had more than the number, not to mention common goals and future dreams.

My ex was 20 years older than I was, she was a princess, lol, and it was the best relationship I have ever had. Mutually went our ways in the end, but still. Statistically speaking yes, younger men or younger people can be at different points in their lives (being immature) than say someone in their mid life or later. but at the same time the opposite is true. I always found I have never meshed well with women my own age, for the reasons of immaturity and lack of goals and such. But I am sure there is like minded women out there of my own age, just as sure as I am that I few of the older women I have dated were very immature :P

If its a question regarding yourself, I would just look past the number and more at the common ground. Is he stable? Does he have goals and is he actually following through to get them etc...
