I submit that young women were not meant to understand male sexuality as if they did, a great many would be so disgusted by its realities, they would cease engaging in sex with men. Coming to terms with the realities of male sexuality is part of the female sexual maturation process.
However, in modernity, where our sex and relationship structures of polite mirage have largely crumbled, laying bare harsher realities, young women must square these more basal systems of male sexuality with normal but different human functioning than their own or risk building mental structures that create disdain for men themselves.
