My mother and father have asked me that question many times. They have long ago given up on the idea of grandchildren... lol.
For myself I am an expat and live in places where it is far more accepted.
But it is mostly because of accessibility, I rarely meet older women.
I have dated a few and I will give some reasons why I set my marks to between 25-35, I am 57. I am pretty loose on the lower range, not so much on the upper.
I have been married 1 time, she was 33 and I was 54 it only lasted 1 year but it didn't end for any reason related to age.
I was with the same woman for 27 years, never wanted to marry, she was my age.
Every older woman I've dated had way too much baggage. We all have it but men tend not to share it while women stack it on the table.
Most women I meet in the upper range have children and I don't have any such desire, I reached this age childless for a reason not because of dumb luck.
Younger women aren't as demanding and seldom nag at you.
My parents ask how I could have anything in common with a much younger woman. I live in outside the US so I don't have anything in common with women of any age, so it doesn't matter.
Younger women are just more fun, they don't tend to be set in their ways and are more adaptive.
Well that is my take.
BTW Lord Enki; you might want to review your math. Were you really married at the age of 3?
