I think that being skinny makes you look older than you are, when you get older...IYSWIM.
My OH is 23 years younger than I but if he didn't like what he sees, (and he doesn't need specs) he could easily get someone 40 years + younger.
I think it's a win for positivity and personality, over a few extra pounds and being relentless and boring about diets, exercise and being a narky, nagging bitch.
IMO it's boring to have a partner who is needy and needs their self confidence boosting every five minutes and who wears so much make-up that the real person is never seen.
Some men don't seem that bothered about moobs, a paunch, hairy back/ears, overgrown eyebrows or non-existent/saggy bums and nor do the women married to men who fit that description.
