The following division of the various phenomena of this psycho-sexual anomaly is made, therefore, in accordance with these clinical facts:—
A. Homo-sexual Feeling as an Acquired Manifestation.—The determining condition here is the demonstration of perverse feeling for the same sex; not the proof of sexual acts with the same sex. These two phenomena must not be confounded with each other; perversity must not be taken for perversion.
Perverse sexual acts, not dependent upon perversion, often come under observation. This is especially true with reference to sexual acts between persons of the same sex, particularly pederasty. Here paræsthesia sexualis is not necessarily at work; but hyperæsthesia, with physical or mental impossibility of natural sexual satisfaction. Thus we find homo-sexual intercourse in impotent masturbators or debauchees, or faute de mieux in sensual men and women in imprisonment, on ship-board, in garrisons, bagnios, boarding-schools, etc.
There is an immediate return to normal sexual intercourse as soon as obstacles to it are removed. Very frequently the cause of such temporary aberration is masturbation and its results in youthful individuals.
Nothing is so prone to contaminate—under certain circumstances, even to exhaust—the source of all noble and ideal sentiments, which arise of themselves from a normally developing sexual instinct, as the practice of masturbation in early years. It despoils the unfolding bud of perfume and beauty, and leaves behind only the coarse, animal desire for sexual satisfaction. If an individual, spoiled in this manner, reaches an age of maturity, there is wanting in him that æsthetic, ideal, pure, and free impulse which draws one toward the opposite sex. Thus the glow of sensual sensibility wanes, and the inclination toward the opposite sex becomes weakened. This defect influences the morals, character, fancy, feeling, and instinct of the youthful masturbator, male or female, in an unfavorable way, and, under certain circumstances, allows the desire for the opposite sex to sink to nil; so that masturbation is preferred to the natural mode of satisfaction.
