Until puberty, sex is submerged, nascent, incipient only.

After puberty, it is a tremendous factor.
What is sex, really?
We can never say, satisfactorily.

But we know so much: we know that it is a dynamic polarity between human beings, and a circuit of force _always_ flowing.

The psychoanalyst is right so far.

There can be no vivid relation between two adult individuals which does not consist in a dynamic polarized flow of vitalistic force or magnetism or electricity, call it what you will, between these two people.
