Hm, I find it weird that women are allowed to have more sexual freedom, but then again I do not. Women always seemed to have more diplomatic immunities than men, and back in the day, men courted women and chivalry was in effect (now it's pretty much dead in most parts). Seeing this I don't find it odd that it seems "normal" for a woman to express her individuality.
It all goes back to the mold of how girls and boys should be raised, this mold is apparently hard to break. This is why men can't do a lot of things that women can. Boys were raised to be "macho" and to "never cry" and yes, girls were raised like ceramic dolls. Even still, it pisses me off when guys act soooo straight and they are afraid to damage their heterosexual reputation by a little act like going through the womens department to get to the restroom (or a similar act).
