I've always looked younger than my age (51), and I always ended up dating younger men. Not deliberately...it just happened that way. My husband is four years younger, and we get along just fine. ;)
My wife has me by a couple of years. My first girlfriend was 17 and I was 14. In between any girlfriends that were younger than I ended in train wrecks. No yearning for 25 year olds here.
