Apparently, it's every man's secret dream to spend a few years having sex with supermodels . . . then find someone nice and homely to settle down with for good.  Who knew?

According to a new study reported by, men say women with more attractive and feminine features are the best for one-night stands . . . and women with less attractive and more masculine features are better to MARRY.

By feminine features, they mean large eyes, small noses, full cheeks, a small jawbone, and a younger overall look.  Those are the kind of women that men said they wanted to have SEX with . . . but not be in relationships with.

The theory here is that men have to worry about more attractive women cheating on them.  And if a woman cheats on you, there's a chance you'll end up raising some other guy's child.  And it's the male biological instinct NOT to do that.

So when it comes to settling down, men aren't necessarily looking for the most attractive woman . . . they're looking for someone who won't cheat on them.
