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?

Now, a new story. The new thrills are passed on to the great upper centers of the dynamic body. The individual polarity now changes, within the individual system. The upper centers, cardiac plexus and cervical plexuses, thoracic ganglion and cervical ganglia now assume positivity. These, the upper polarized centers, have now the positive r�le to play, the solar and the hypogastric plexuses, the lumbar and the sacral ganglia, these have the submissive, negative r�le for the time being.
