I married a woman 16 years younger than me.
It was a bad move.
Not because she was young, but because she wasn't marriage material. But I didn't know that then. I found out. My fault.
I like the young ones. I was out with a 22yo the other night. We had a blast.
Age, in and of itself, simply doesn't matter. I recently had a 2 month run with a divorced, 35yo mother of two. Everything was fine. Until she finally started to believe me about "no commitment." She moved on. Ok with me.
You can run around with young women all you want. Just be careful about LTR's with them. And don't marry them. Better yet, don't marry at all, ever. (And I'm pretty down on LTRs, too. I think I'm done with them, really. No more.)
You can have LOTS of fun and really nice times with young women. Just don't expect too much from them.
