I was gonna add breathing to the list, but i see I don't need to...
Even my liberal sister had an epiphany about this not long ago. I was so proud of her. She said " if it weren't for sex, men would have nothing to do with women, and if it weren't for children, women would have nothing to do with men"
True Words.
I'm pretty sure women want sex as much or more than men, but they have the luxury of pretending they don't, as its generally pretty readily available to them. Women want you to want them, and assume that you do. If you don't, and they realize that, it seems to mess with their heads pretty good and they get quite irate.
If you look at the general behavior of women, it pretty closely mimics the behavior of anyone who's been given too much power and almost zero accountability. I'm not convinced they are as complex as we've been led to believe.
One thing I'm quite sure of, the vast majority of women care most if you think they are attractive. As long as you find them attractive, they don't mind if you think they are also a class A bitch. If you find them unattractive but a wonderful person, they would rather have it the other way around.
