What the hell are your problems?
You guys are just fucking crazy. You should treat girls exactly the way you treat guys. Don't abuse them. But, don't act all lovey-dovey around them just because they have a vagina.
I guarantee you that if you abuse girls, and one of the nice guys comes along, she's going to beg them to get away from you. I don't blame her.
I don't think this movie is trying to tell us to abuse girls, I think it's just saying how girls (and guys) can be sometimes. You can give 'em everything they've ever wanted, and they wouldn't know it.
Anyway, I hope you learn your lesson that sex isn't everything when you're burning in Hell.
