It's no mystery why women shave their bodies: marketing and shame nowadays. The razor companies decimated any social thought of how hair looked on the legs and face. Now it's part of our "identity". Look at the previous shaving thread where women were called disgusting or it's gross to have hairy legs. There is social pressure. You may enjoy it now but you have to wonder how it came to be.
But that goes for EVERYTHING. I mean as long as there has been society people for the most part have wanted to fit in so if less hairy women was deemed beautiful by society they would get picked by worthy suitors and the ones that aren't naturally hairy fake it with plucking and shaving.
The same can be said about any gender roles from how a male is supposed to act with his friends, parents, job and love interest to how women should behave as a mom. This whole idea of self identity is not something that any real culture or society accepts. Individuality is usually a lie. There is nothing idividual about liking and buying mass produced items and associating a brand with yourself.
Society works and accepts people that don't stand out too much. And if you chose to stand out in society you have to be exceptional in some category where society allows it because they envy your natural beauty or skill.
