Do you think that girls/women in America are pressured by society into living up to some impossible ideal, where as men aren't?

I think so…..either that, or the men/boys just don’t respond to the “pressure” of living up to looking like a dapper a GQ cover model, or one of the Whatever Pop Singer Brothers (Sorry Rangerr! You know who I mean!) Men / boys don’t seem feel like they need to look like some sexy movie star, whereas the girls kill themselves emulating Britney Spear and such crap as that….
Why do you think that is? Is it society putting pressure on, or have women/girls always done that, throughout the ages, and society just responded?
