But what is the experience? Untellable. Only, we know something. We know that in the act of coition the _blood_ of the individual man, acutely surcharged with intense vital electricity--we know no word, so say "electricity," by analogy--rises to a culmination, in a tremendous magnetic urge towards the magnetic blood of the female. The whole of the living blood in the two individuals forms a field of intense, polarized magnetic attraction. So, the two poles must be brought into contact. In the act of coition, the two seas of blood in the two individuals, rocking and surging towards contact, as near as possible, clash into a oneness. A great flash of interchange occurs, like an electric spark when two currents meet or like lightning out of the densely surcharged clouds. There is a lightning flash which passes through the blood of both individuals, there is a thunder of sensation which rolls in diminishing crashes down the nerves of each--and then the tension passes. The two individuals are separate again. But are they as they were before? Is the air the same after a thunder-storm as before? No. The air is as it were new, fresh, tingling with newness. So is the blood of man and woman after successful coition. After a false coition, like prostitution, there is not newness but a certain disintegration. But after coition, the actual chemical constitution of the blood is so changed, that usually sleep intervenes, to allow the time for chemical, biological readjustment through the whole system. So, the blood is changed and renewed, refreshed, almost recreated, like the atmosphere after thunder. Out of the newness of the living blood pass the new strange waves which beat upon the great dynamic centers of the nerves: primarily upon the hypogastric plexus and the sacral ganglion. From these centers rise new impulses, new vision, new being, rising like Aphrodite from the foam of the new tide of blood. And so individual life goes on. Perhaps, then, we will allow ourselves to say what, in psychic individual reality, is the act of coition. It is the bringing together of the surcharged electric blood of the male with the polarized electric blood of the female, with the result of a tremendous flashing interchange, which alters the constitution of the blood, and the very quality of _being_, in both. And this, surely, is sex. But is this the whole of sex? That is the question. After coition, we say the blood is renewed. We say that from the new, finely sparkling blood new thrills pass into the great affective centers of the lower body, new thrills of feeling, of impulse, of energy.--And what about these new thrills?
