"Imagine what would happen if instead of centering our beliefs about heterosexual sex around the idea that the man "penetrates" the woman, we were to say that the woman's vagina "consumes" the man's penis. This would create a very different set of connotations, as the woman would become the active initiator and the man would be the passive and receptive party. One can easily see how this could lead to men and masculinity being seen as dependent on, and existing for the benefit of, femaleness and femininity."
