It is true from early habit, one must make love mechanically as one swims; I was once very fond of both, but now as I never swim unless I tumble into the water, I don't make love till almost obliged.
Sex was always surrounded by taboos, and I don't see it necessarily as a manifestation of evil. I think that sexuality is first and foremost the way that God chooses for us to be here on earth, to enjoy this energy of love in the physical plane.
