“Sex for pleasure with various partners is therefore more “human” than animal. Strictly reproductive, once-in-a-blue-moon sex is more “animal” than human. In other words, an excessively horny monkey is acting “human,” while a man or woman uninterested in sex more than once or twice a year would be, strictly speaking, “acting like an animal.”
