Man’s historic remedy for this defect in himself—namely, shutting up his woman behind the doors of a harem—and the remedy that followed this, of shutting her in behind psychic bars of repressions and inhibitions, is the infantile method of force. Its success has been slight. The only thing that doors and locks confine is the body, and perhaps that was all he wanted. And likewise the only thing that inhibitions and bars of repression can restrain is the physical manifestation of the sexual impulse. The instinct itself cannot be annihilated. We know quite well what happens to different types of people when the expression of the sexual impulse is completely inhibited. Man or woman is equally affected by this suppression, but woman in general has been the more suppressed. § 104 It cannot be overlooked that the constant pull exercised over every woman by her erotic instincts, even though they be so repressed that she is utterly unconscious of them, is more racking in the more refined and cultivated type of woman than in the other. Lacking the satisfaction of her erotic desires she unconsciously seeks gratification in numerous activities toward which this blind erotism is the only efficient cause. And as the real need is never met, these substitute activities never completely satisfy. § 105 The practice of Karezza, or the husband’s reserving his own erotic acme, has an interesting sidelight thrown upon it by the experiments of Steinach in cutting the _vas deferens_. The effect of this is to stop the external secretions of the interstitial gland. “The result is that the seminal vesicle (either one of the two reservoirs for the semen) and the interstitial gland are completely cut off from one another; and this in turn gives rise to a multiplication of the interstitial cells, and to an increase of the hormone produced by them. “Professor Steinach has performed the operation on men on several occasions. In some instances these men were fairly young but physically weak; in others the subjects were senile men. The appearance of the subjects became youngish, fresh; their bodily strength increased, the tremor of their hand disappeared, memory and will power returned, and the sexual power was restored.”[21]
