If a man already has older children, would he prefer women in their 30's and 40's?

I'll refer to my manager's case:

He's 50 years old and 3 adult children are 32 years, 28 and 20 years old. He has grandchildren already too. He just recently got engaged last month. His fiance is 39 years old and has two kids of her own too; both in their mid teen years.

Is that one of the times when a man doesn't go for woman in their 20's anymore? If he already has children (and grandchildren) and doesn't want anymore.

If a man already has older children, would he prefer women in their 30's and 40's?
