what is something about girls that guys dont know?

This: women and girls, especially inexperienced girls, often react to unwelcome sexual advances by kind of "freezing." If she goes dead silent and does or says nothing when being sexually touched, guys may assume she wants ir or likes it. This leads to many misunderstandings, and the often heard guys' complaint that she "agreed" to have sex then changed her mind the next day and said she was assaulted.

No, she didn't agree, technically. It's an important distinction. If she is actively helping you undress, and hungrily kissing you, those are signs she is into it. If she is looking away or kind of burying her face in the covers or your chest, she might actually be too frightened to speak up, and beware you might be accused of rape if you proceed.

Pull back. Ask her. Search her face for the truth. And if you can't get her to admit she wants it...stop.

The pain women go through when they are on their period.
Guys don't know a damn thing about that.

We only keep you around so you can open jars for us and so we can "borrow" your hoodies.

Putting war paint on.........I mean make-up!

lol last i checked, guys were pretty much in tuned with knowledge about girls. more so than girls are about guys.
