Listen, I bedded down women 10 years younger than me, but when it came to relationship material, it happened that older women rose to the top... YMMV but I noticed these things:
As an older man in my 40's it is about women who have a similar timeline and experiences. My kids are older....Women 10 years younger than me still have kids in elementary school. If they don't have kids, most want to have a family soon. I decided I was done with young kids.
I'm in upper mgmt. I don't really want to date a woman in a position that I would supervise if we worked together. I want an intellectual equal who can match my drive and passion.
Age differences are less meaningful the older you get. the "1/2 your age plus 7" rule for the lower end of a dating couple bears that out.
If a woman is as concerned with her looks at 50 as she is at 30 she will be a hot 50 year old. Example: Demi Moore. If a woman is in shape at 40 she will likely keep off the extra weight the next few years. How many hot 20 year olds ballooned up to obese in the next 10 years from my experience? Most of them...FWIW "thicc" is not my thing.
I wanted someone who was equivalent to me in sports and athleticism. When I turned 40 I was running times with the top 50 year old female ultramarathoners in my area. I came to appreciate the toughness of these older women.
I lead a rugged outdoor life. Most of these 20 year old "10's" guys fawn over are too worried about breaking a nail or missing a hair appt. doing stuff outside and getting sweaty and dirty. SO that eliminates a big portion of the "top end" women for me....
Older women have frequently "outgrown" their previous spouses and partners. Their energy is a lot more positive and realistic than that of younger girls. They are no-bullsh1t about sex. they aren't afraid to tell you they want it.
Older women have the time and money to do things. They might have gotten the cabin at the lake in the divorce, they might have an inheritance from their parents. They usually are not shy about contributing financially to a good time.
Folks joke about Cougar-Cub...it ain't that way with the right one...it's more like Lion and Lioness
