But this is mistaken. Sex has always been formed by someone outside of ourselves. By its very nature, sex involves the self-giving of a man and a woman. Only if sex is conceived of as a technique for personal pleasure or power can we reasonably say that it should be entirely private and free from external limits and obligations. And sex as personal pleasure or power is a perversion. It is an impoverished form of physical love, “tiny and meaningless and—sad-making.”
