" when sex is conceptualized as a need, it creates an environment that fosters men’s sense of sexual entitlement. Nicholas Kristof and Sheryl WuDunn’s book Half the Sky illustrates how the assumption that boys require outlets to “relieve their sexual frustrations” facilitates the sexual enslavement of impoverished girls. If you think of sex as a drive, like hunger or thirst, that has to be fed for survival, if you think that men in particular—with their 75 percent spontaneous desire—need to relieve their pent-up sexual energy, then you can invent justifications for any strategy a man might use to relieve himself. Because if sex is a drive, like hunger, then potential partners are like food. Or like animals to be hunted for food. "
