From what I've seen around me, men seem to be happiest with average-sized/curvier women.
A colleague of mine is a football player and very into fitness and his girlfriend is quite overweight, they've been together 6 years.
A man I liked who is quite thin, he wasn't interested. His ex is at our workplace and is significantly overweight.
I know this sounds nasty and rude, it probably is. However I feel like on the whole men aren't that bothered about women having figures like Victoria's Secret models, and personality is more important.
