Cabanis, in his famous and pioneering work, _Rapports du Physique et du Moral_, said in 1802, that women not only bear sexual excess more easily than men, but sexual privations with more difficulty, and a cautious and experienced observer of to-day, Löwenfeld (_Sexualleben und Nervenleiden_, 1899, p. 53), while not considering that normal women bear sexual abstinence less easily than men, adds that this is not the case with women of neuropathic disposition, who suffer much more from this cause, and either masturbate when sexual intercourse is impossible or fall into hystero-neurasthenic states. Busch stated (_Das Geschlechtsleben des Weibes_, 1839, vol. i, pp. 69, 71) that not only is the working of the sexual functions in the organism stronger in women than in men, but that the bad results of sexual abstinence are more marked in women. Sir Benjamin Brodie said long ago that the evils of continence to women are perhaps greater than those of incontinence, and to-day Hammer (_Die Gesundheitlichen Gefahren der Geschlechtlichen Enthaltsamkeit_, 1904) states that, so far as reasons of health are concerned, sexual abstinence is no more to be recommended to women than to men. Nyström is of the same opinion, though he thinks that women bear sexual abstinence better than men, and has discussed this special question at length in a section of his _Geschlechtsleben und seine Gesetze_. He agrees with the experienced Erb that a large number of completely chaste women of high character, and possessing distinguished qualities of mind and heart, are more or less disordered through their sexual abstinence; this is specially often the case with women married to impotent men, though it is frequently not until they approach the age of thirty, Nyström remarks, that women definitely realize their sexual needs.
