Context, I’m 30 now and i will find women my age and up attractive, but 15 years ago a 35 year old women would never have been attractive to me.
As I’ve aged younger women are less and less attractive (thankfully)
But when I’m 60 will 60 year old women be attractive to me?

They are kind of stuck. They have to find companions who don’t have children or responsibilities. The best majority of the people who land in those categories are younger folks.
