How To Act Ladylike

What does it mean to be a woman in America?
I wish I knew. 
Thus far in time, I've come up with a couple points based off what I've been told. 

A woman has to get married and have kids. 
She can't do it too young or too old though, there's a time frame for human incubators.

A woman can't be in tune with her sexuality, or else she's too promiscuos.
She does also have to be in tune with her sexuality, or else she's a prude. 

A woman has to be intelligent and speak up for her beliefs.
She can't speak up if a man disagrees though, or else she's being rude.

A woman has to achieve big things in life, and set an example for others.
She can't brag or be proud of her achievements, no one likes an arrogant lady. 

 Those are just some of the things I've heard about being a woman. 
Notice how they make absolutely no sense? At least to me, they don't.

For the record; there is not a singular man on this planet who can give me input on what I'm supposed to be.
If I ever discover how to properly be a woman, I'll make sure to let you know.
