[203] "One of my patients," remarks Dr. R.T. Morris, of New York, (_Transactions of the American Association of Obstetricians_, for 1892, Philadelphia, vol. v), "who is a devout church-member, had never allowed herself to entertain sexual thoughts referring to men, but she masturbated every morning, when standing before the mirror, by rubbing against a key in the bureau-drawer. A man never excited her passions, but the sight of a key in any bureau-drawer aroused erotic desires." [204] Freud (_Drei Abhandlungen zur Sexualtheorie_, p. 118) refers to the sexual pleasure of swinging. Swinging another person may be a source of voluptuous excitement, and one of the 600 forms of sexual pleasure enumerated in De Sade's _Les 120 Journées de Sodome_ is (according to Dühren) to propel a girl vigorously in a swing. [205] The fact that horse exercise may produce pollutions was well recognized by Catholic theologians, and Sanchez states that this fact need not be made a reason for traveling on foot. Rolfincius, in 1667, pointed out that horse-riding, in those unaccustomed to it, may lead to nocturnal pollutions. Rohleder (_Die Masturbation_, pp. 133-134) brings together evidence regarding the influence of horse exercise in producing sexual excitement. [206] A correspondent, to whom the idea was presented for the first time, wrote: "Henceforward I shall know to what I must attribute the bliss--almost the beatitude--I so often have experienced after traveling for four or five hours in a train." Penta mentions the case of a young girl who first experienced sexual desire at the age of twelve, after a railway journey. [207] Langdon Down, _British Medical Journal_, January 12, 1867. [208] Pouillet, _L'Onanisme chez la Femme_, Paris, 1880; Fournier, _De l'Onanisme_, 1885; Rohleder, _Die Masturbation_, p. 132. [209] _West-Riding Asylum Reports_, 1876, vol. vi. [210] _Das Nervöse Weib_, 1898, p. 193. [211] In the Appendix to volume iii of these _Studies_, I have recorded the experience of a lady who found sexual gratification in this manner. [212] Dr. J.G. Kiernan, to whom I am indebted for a note on this point, calls my attention also to the case of a homosexual and masochistic man (_Medical Record_, vol. xix) whose feelings were intensified by tight-lacing. [213] Some women are also able to produce the orgasm, when in a state of sexual excitement, by placing a cushion between the knees and pressing the thighs firmly together. [214] _Leçons sur les Déformations Vulvaires_, p. 64. Martineau was informed by a dressmaker that it is very frequent in workrooms and can usually be done without attracting attention. An ironer informed him that while standing at her work, she crossed her legs, slightly bending the trunk forward and supporting herself on the table by the hands; then a few movements of contraction of the adductor muscles of the thigh would suffice to produce the orgasm.
