Venery, or continued thought thereon, saps the nervous energies. The enervating influence of neither of these aspects of sex life has received the general recognition which it demands. One of the most outstanding causes of physical and mental enervation is venereal excess. This is the chief cause, the ground work, of impotency. This deficiency receives little attention from doctors and little is done by way of restoring potency. Instead, sex stimulants (aphrodisiacs) are used, a quackish manner of treating patients who need information, not damnation.

Sexual unrest, sexual starvation, sexual excesses and abuses are great nerve strains. It is neither healthy nor normal to excite an appetite continually without gratifying it. Continually dwelling on sexual subjects (mental erotism) and sexual dalliance often produce more damage than actual indulgence. He who desires moderation in his sex life should avoid exposing himself to continued excitement by too great intimacy with the opposite sex and other sources of sexual excitement.
