I would think that most people prefer a great steak dinner. If steak was not available, then one could settle for a hamburger. If hamburg was not available then I'd guess a small loaf of yesterday's bread would have to do. If that wasn't handy, then perhaps a moldy orange. No moldy orange? A frog will have to suffice.
The hunger drive is not one your body takes lightly and many have been known to eat all sorts of repulsive things when starving. Sex is like that and I'd suppose that it's often a case of "any port in a storm", as the sailors used to say. I know of one single mom whose periods of abstinence rarely exceed 3 months at which time she is 'driven' to take on whatever is available. After the 'honeymoon' is over, she'll go back to her search for a "good man", which she will never find because good men rarely like to make a commitment to a woman who cannot keep her panties on for very long. Anyway, I think this drive accounts for much of the sodomy in prisons, on shipboard and also alot of what else is going on in the ever-growing american ghettos.
Sex, unlike food, is not necessary for survival of the individual. The drive to consummate lasts until one dies. Celibacy has never shortened anyone's life but where does the balance lie? Other than being a hermit or monk, the other extreme is complete abandonment of any qualification or standards. This is especially disastrous far beyond the disease risk for it always brings into existence children who were not wanted. The 10,000,000 abortions this country experiences annually attests to the fact that the sex urge was followed without regard for consequences. Venereal disease is endemic and birth control devices are major consumer items. People seem not to care as long as they "get it".
Wars are fought over food, and wars are not very constructive. In periods of affluence and/or peace, unbridled sex ruins a civilization as assuredly as does one's conquering enemy.
