Krafft-Ebing was of opinion that women require less sexual satisfaction than men, being less sensual. (Krafft-Ebing, "Ueber Neurosen und Psychosen durch sexuelle Abstinenz," Jahrbücher für Psychiatrie, 1888, Bd. viii, ht. I and 2.)

"In the normal woman, especially of the higher social classes," states Windscheid, "the sexual instinct is acquired, not inborn; when it is inborn, or awakes by itself, there is abnormality. Since women do not know this instinct before marriage, they do not miss it when they have no occasion in life to learn it." (F. Windscheid, "Die Beziehungen zwischen Gynäkologie und Neurologie," Zentralblatt für Gynäkologie, 1896, No. 22; quoted by. Moll, Libido Sexualis, Bd. i, p. 271.)

"The sensuality of men," Moll states, "is in my opinion very much greater than that of women." (A. Moll, Die Konträre Sexualempfindung, third edition, 1899, p. 592.)

"Women are, in general, less sensual than men," remarks Näcke, "notwithstanding the alleged greater nervous supply of their sexual organs." (P. Näcke, "Kritisches zum Kapitel der Sexualität," Archiv für Psychiatrie, 1899, p. 341.)

Löwenfeld states that in normal young girls the specifically sexual feelings are absolutely unknown; so that desire cannot exist in them. Putting aside the not inconsiderable proportion of women in whom this absence of desire may persist and be permanent, even after sexual relationships have begun, thus constituting absolute frigidity, in a still larger number desire remains extremely moderate, constituting a state of relative frigidity. He adds that he cannot unconditionally support the view of Fürbringer, who is inclined to ascribe sexual coldness to the majority of German married women. (L. Löwenfeld, Sexualleben und Nervenleiden, 1899, second edition, p. 11.)

Adler, who discusses the question at some length, decides that the sexual needs of women are less than those of men, though in some cases the orgasm in quantity and quality greatly exceeds that of men. He believes, not only that the sexual impulse in women is absolutely less than in men, and requires stronger stimulation to arouse it, but that also it suffers from a latency due to inhibition, which acts like a foreign body in the brain (analogous to the psychic trauma of Breuer and Freud in hysteria), and demands great skill in the man who is to awaken the woman to love. (O. Adler, Die Mangelhafte Geschlechtsempfindung des Weibes, 1904, pp. 47, 126 et seq.; also enlarged second edition, 1911; id., "Die Frigide Frau," Sexual-Probleme, Jan., 1912.)

It must not, however, be supposed that this view of the natural tendency of women to frigidity has everywhere found acceptance. It is not only an opinion of very recent growth, but is confined, on the whole, to a few countries.

"Turn to history," wrote Brierre de Boismont, "and on every page you will be able to recognize the predominance of erotic ideas in women." It is the same today, he adds, and he attributes it to the fact that men are more easily able to gratify their sexual impulses. (Des Hallucinations, 1862, p. 431.)

The laws of Manu attribute to women concupiscence and anger, the love of bed and of adornment.

The Jews attributed to women greater sexual desire than to men. This is illustrated, according to Knobel (as quoted by Dillmann), by Genesis, chapter iii, v. 16.
