Society

Today I went to my girlfriends room to hang out. On her wall she had some Taylor Latner poster, I was ok with it because its just a poster, but because I am feisty I was giving her crap about having a half naked man on her wall. While I was giving her crap something came up, I asked her if I could also have a picture of a girl on my wall. She said it was ok as long as the girl had pants and a shirt on, because thats what he has on in his poster. I looked online for posters and even at walmart, there is hardly any posters of girls in pants and a shirt, and thats what goes on in our society girls dress in skimpy clothes and are oooed and ahhed but when most guys do it, it is just wrong. So who choose's this and why does it have to be like that? It just doesn't make sense to me.
