[339] With regard to the physical signs, the same conclusion is reached by Legludic (in opposition to Martineau) on the basis of a large experience. He has repeatedly found, in young girls who acknowledged frequent masturbation, that the organs were perfectly healthy and normal, and his convictions are the more noteworthy, since he speaks as a pupil of Tardieu, who attached very grave significance to the local signs of sexual perversity and excess. (Legludic, _Notes et Observations de Médecine Légale_, 1896, p. 95.) Matthews Duncan (_Goulstonian Lectures on Sterility in Women_, 1884, p. 97) was often struck by the smallness, and even imperfect development, of the external genitals of women who masturbate. Clara Barrus considers that there is no necessary connection between hypertrophy of the external female genital organs and masturbation, though in six cases of prolonged masturbation she found such a condition in three (_American Journal of Insanity_, April, 1895, p. 479). Bachterew denies that masturbation produces enlargement of the penis, and Hammond considers there is no evidence to show that it enlarges the clitoris, while Guttceit states that it does not enlarge the nymphæ; this, however, is doubtful. It would not suffice in many cases to show that large sexual organs are correlated with masturbation; it would still be necessary to show whether the size of the organs stood to masturbation in the relation of effect or of cause. [340] Thus, Bechterew ("La Phobie du Regard," _Archives de Neurologie_, July, 1905) considers that masturbation plays a large part in producing the morbid fear of the eyes of others. [341] It is especially an undesirable tendency of masturbation, that it deadens the need for affection, and merely eludes, instead of satisfying, the sexual impulse. "Masturbation," as Godfrey well says (_The Science of Sex_, p. 178), "though a manifestation of sexual activity, is not a sexual act in the higher, or even in the real fundamental sense. For sex implies duality, a characteristic to which masturbation can plainly lay no claim. The physical, moral, and mental reciprocity which gives stability and beauty to a normal sexual intimacy, are as foreign to the masturbator as to the celibate. In a sense, therefore, masturbation is as complete a negative of the sexual life as chastity itself. It is, therefore, an evasion of, not an answer to, the sexual problem; and it will ever remain so, no matter how surely we may be convinced of its physical harmlessness." [342] "I learnt that dangerous supplement," Rousseau tells us (Part I, Bk. III), "which deceives Nature. This vice, which bashfulness and timidity find so convenient, has, moreover, a great attraction for lively imaginations, for it enables them to do what they will, so to speak, with the whole fair sex, and to enjoy at pleasure the beauty who attracts them, without having obtained her consent."
