Interesting question.
The first thing to come to mind was something about growing up with constant little annoyances relating to other peoples' expectations.
It's an ever ongoing process navigating around those expectations. From small things in childhood like "you don't want to play with those kinds of toys, do you?" "you can't wear those shoes" to later on when friends start pushing you to like boys and wear certain things and they get angry with you or question your identity if you don't conform, to adulthood when your family and peers put pressure on you to think about marrying and having children.
Womanhood feels like there's a set standard, certain way of doing things, that was decided for you long ago, and everyone seems to agree about it. Everyone seems to be in on it. And you just have to keep telling yourself to power through it all and that it's okay to go your own way. Even if it feels bad not being able to meet all the expectations of the "ideal" womanhood, it will feel so much worse if you attempt it at all costs and in the process abandon yourself.
I'm sorry if that's not a good answer. It's just my first thoughts.
