This dependence, however, differs from the manifestations of normal life only in the intensity of the sexual feeling that here comes in play, and in the slight degree of will-power necessary for the maintenance of its equilibrium. The difference is one of intensity, not of quality, as in masochistic manifestations. This dependence of one person upon another of the opposite sex, that is abnormal but not perverse,—a phenomena possessing great interest when regarded from a forensic stand-point,—I designate “_sexual bondage_;”[78] for the relations and circumstances attending it have in all respects the character of bondage. The will of the ruling individual dominates that of the person in subjection, just as a master’s does his bondsman’s.[79] This “sexual bondage,” as has been said, is certainly an abnormal phenomenon. It begins with the first deviation from the normal. The degree of dependence of one person upon another, or of two upon each other, resulting from individual peculiarity in the intensity of motives that in themselves are normal, constitutes the normal standard established by law and custom. Sexual bondage is not a perverse manifestation, however; the instinctive activities at work here are the same as those that set in motion—even though it be with less violence—the psychical vita sexualis which moves entirely within normal limits. Fear of losing the companion and the desire to keep him always satisfied, amiable, and inclined to sexual intercourse, are here the motives of the individual in subjection. An extraordinary degree of love—which, particularly in woman, does not always indicate an unusual degree of sensuality—and a weak character are the simple elements of this extraordinary process.[80] The motive of the dominant individual is egoism, which finds unlimited room for action. The manifestations of sexual bondage are various in form, and the cases are very numerous.[81] At every step in life we find men that have fallen into sexual bondage. Among married men, hen-pecked husbands belong to this category, particularly elderly men who marry young wives and try to overcome the disparity of years and physical defects by unconditional submission to the wife’s every whim; and unmarried men of ripe maturity, who seek to better their last chance of love by unlimited sacrifice, are also to be enumerated here. Here belong, also, men of any age, who, seized by hot passion for a woman, meet coldness and calculation, and have to capitulate on hard conditions; men of loving natures who allow themselves to be persuaded to marriage by notorious prostitutes; men who, to run after adventuresses, leave everything and jeopardise their future; husbands and fathers who leave wife and child, to lay the income of a family at the feet of a harlot.
