To the newcomers to the OP's point, I still say a healthy male does not care about how a female looks. As long as she is reasonably healthy, he will mount her. This choicey look at female looks has more to do with a culture obsessed with monogamy and making money off female insecurities.
It's the female who will care about how the male looks because that's one factor in determining the genetic makeup which she is choosing for her kids. The male's genetic continuity is virtually inexhaustible in a primitive setting (the one our brains are most evolved and geared to) because he can have as many wives as he's able to achieve, basically.
In a monogamous setting, the male has to consider which female he will choose to best continue his genes. This is because he is now investing in just one egg basket (literally). This is not a natural choice for him, so he's less evolved to make that decision.
