But we are now in the odd position of supposing that sex is too trivial to require virtue for its exercise, but that it is simultaneously so significant, so determinative of a person’s identity, that to suggest any restraint upon its consensual exercise is an affront to the most important fount of human dignity. It is at once nugatory and holy. We are at once to think nothing of it, and everything. It is at once like scratching an itch, and worshiping a god. It requires no sacrifice from its exerciser, and the sacrifice of everything else to it: the welfare of children and the family, public morals, the common good, and liberty itself.
