"…where a man does not engage in communicative sexuality, he acts either out of reckless disregard, or out of willful ignorance. For he cannot know, except through the practice of communicative sexuality, whether his partner has any sexual reason for continuing the encounter. And where she does not, he runs the risk of imposing on her what she is not willing to have. All that is needed, then, in order to provide women with legal protection from date rape is to make both reckless indifference and willful ignorance a sufficient condition of mens rea, and to make communicative sexuality the accepted norm of sex to which a reasonable woman would agree."
