Most of society's heterosexual, the opposite gender's preferences become social expectations of your own gender, social expectations become measures of self esteem.
This can be used to explain several phenomena:
It's with a subconscious belief that women desire masculine traits that men call each other pussies.
It's with a subconscious belief that men desire sexual exclusivity that women call each other sluts.
It's why women might dress sexy to make themselves feel good by associating I themselves with beautiful women idealized in society.
It's why men might take a lot of risks to make themselves feel good by associating themselves with heroic men idealized by society.
But... there might be contradicting evidence on this:
If my memory's not failing me, I believe I've read a study that found a strong correlation between risky and risk-averse behaviors with different levels of testosterone between individuals of each gender.
This suggests that even within women, who experience the feminine side of social expectations and might have absolutely no desire to gain the approval or sexual favor of other women, higher level of testosterone still result in more risk taking, and like wise men who get exposed to the same social expectations as much as any other men will still be more risk averse if they have lower testosterone levels. This suggests a more direct relationship between risk taking and biology (Although sociological mechanisms can still be a factor).
I think I've read this in paper form, but if you'd like I can try and find an online source.
