Regarding the comments about art imitating life, women flaunting their bodies and whatnot...it's important to remember that women are still largely valued by their sexual attractiveness. Of course I'm not speaking for all women, but the fact that we sometimes feel empowered by looking sexy doesn't actually give us any power and doesn't make the constant sexualised depictions of females okay.
It may be true that women's fashion can accentuate the sexual aspects of our bodies, but that doesn't mean it should be accepted as the norm and remain unchallenged. Sex positivity is a great thing, but with sexual politics being what they are we simply can't ignore the fact that women are still very much considered sexual objects, even when this is portrayed in more subtle ways like in women's fashion and beauty culture.
This is a really tricky subject and there are a lot of factors involved, so I'm probably not articulating my point that well. As such I actually agree with those who think there should be a bit more male sexualisation/objectification (and less such treatment of females this way) to even things out. Ideally we'd have a breadth of material in our entertainment - some sexualised, some not, but definitely less slanted towards a particular demographic than it is right now.
