OT: Different rules for different sexes?

Why is it ok for the MR guys to post raunchy pix of women, discuss raunchy topics, etc. but when us gals talk about Perry's lips or the band wearing only socks, it's disgusting? I don't get these double standards. I also think that what us women have said on here is much tamer than most of what the men post. So why is it sickening for them to have to see our stuff & why are we teenagers for admiring male bodies, but they're mature men for looking at naked boobs?
