THE PROBLEM OF SEXUAL EXCITEMENT

It remains entirely unexplained whence the sexual tension comes which originates simultaneously with the gratification of erogenous zones and what is its nature. The obvious supposition that this tension originates in some way from the pleasure itself is not only improbable in itself but untenable, inasmuch as during the greatest pleasure which is connected with the voiding of sexual substance there is no production of tension but rather a removal of all tension. Hence, pleasure and sexual tension can be only indirectly connected.
The Rôle of the Sexual Substance. - Aside from the fact that only the discharge of the sexual substance can normally put an end to the sexual excitement, there are other essential facts which bring the sexual tension into relation with the sexual products. In a life of continence the sexual activity is wont to discharge the sexual substance at night during pleasurable dream hallucinations of a sexual act, this discharge coming at changing but not at entirely capricious intervals; and the following interpretation of this process - the nocturnal pollution - can hardly be rejected, viz., that the sexual tension which brings about a substitute for the sexual act by the short hallucinatory road is a function of the accumulated semen in the reservoirs for the sexual products. Experiences with the exhaustibility of the sexual mechanism speak for the same thing.
