Raised testosterone levels amplify the need for dominance. Therefore more testosterone more dominance, dominance leads to the need to feel like the stronger human being. This in turn builds the rigid social guidelines you mentioned. Therefore the need to appeal to these rules=to the level of testosterone times x. X being the correlation. By having more testosterone you are more insecure about coming out of your shell because of your pride.
Women have far less testosterone than women so will then more openly defy the social guidlines.
Of course for women they barely exist to begin with because they lack the testosterone to bring them forth in the first place.
