We have to be careful here. We need to qualify the difference between sexually attractive and attractive qualities in a partner. That is the difference between what may make us horny and what we would actually want to live with.

I think that's important to note. It's my impression that, regardless of what gender you are, the kind of person you'd be most eager to have a one-night stand with isn't the kind of person you'd be most eager to marry. The "virgin/whore dichotomy" doesn't apply to just women.

I think most het men know quite well what is sexually attractive to them. We have a very simple function to work out (young and shapely). See any top100 girls fhm list in all its monotony. Compare it to the mixture of age ranges/body types you get in this list .

I suspect that male attraction is actually more complicated than conventional wisdom would hold, and that attraction to other factors gets attributed to physical appearance. For example, Tina Fey wasn't "hot" until after she became famous and successful.

The attractive qualities in a partner are more complex and men are probably equally bad at knowing this.

Definitely.
