Lesbian love merits special mention. Owing to the clitoris being more or less concealed, women are often not satisfied by coitus, especially when the ejaculation of the male takes place too quickly. Consequently a number of normal women prefer to procure an orgasm by means of lesbian love (_cunnilingus_.) There are clubs of female perverts, many of whom are not homosexual by heredity. Although they differ from hereditary perversions, acquired perversions are connected with the former by a series of latent hereditary dispositions, more or less marked, and often difficult to distinguish in particular cases, especially when suggestion is blended with them. Among the entirely hereditary and congenital sexual perversions, many occur in individuals who are well conducted and often possessed of delicate and altruistic sentiments. This point is not sufficiently recognized. Such persons are nearly always more or less neurotic in other respects. They are disheartened by their perversion and are so much ashamed of it that they often prefer to carry their secret to the grave rather than confide it to their doctor. Others sometimes confess to a doctor, and the life of a martyr, who is always contemplating suicide, is revealed to him. Individuals of feeble, cynical, egoistic or abnormal natures, whose number is legion in the corrupt centers of modern civilization, yield to their perversion and often come before the tribunals, or else become objects of public contempt. As it is this class which generally become known, it is assumed by too hasty generalization that sexual perverts are necessarily cynical, vicious or weak-minded individuals; but this induction is false. It is unfortunately impossible to estimate the number of sexual perversions dissimulated by a large number of pessimists of both sexes, generally celibate and usually males. I do not pretend that, when sexual perversion is neither hereditary nor favored by a latent hereditary predisposition, nor developed or fixed by alcoholism, it is usually possible to cure it by suggestion. This often acts even in cases where alcohol has aroused a hereditary taint. The incorrigible recidivists among the sexual perverts are, I am convinced, either hereditary or strongly predisposed, or degenerated by alcoholism. The original will power of the pervert is also of great importance. Weak-willed perverts always tend to relapse. The social sanitation of sexual intercourse would certainly reduce to a minimum the compensatory perversions of normal persons who abstain from alcohol. The prohibition of alcoholic drink would definitely eliminate not only the perversions directly due to alcohol, but gradually also those due to alcoholic blastophthoria in the descendants. Other hereditary perversions, not of alcoholic origin, can only be definitely eliminated by healthy selection.
