I'm 55 I find young women very attractive but I wouldn't have sex with them. Sex changes as you get older. It slows down and it's more psychological than physical.
I was starting to question myself here lol everyone acting like a hot 20 year old is no longer hot when you're older meanwhile I see someone I consider attractive they're always attractive, I just won't approach them if they're young.
The only way this doesn't work is "upward" for me. 40s weren't attractive when I was younger but they are now, but a hot 20 year old will always be hot to me (I think).
