Hair-pins have, above all, been found in the female bladder with special frequency; this point is worth some consideration as an illustration of the enormous frequency of this form of auto-erotism. The female urethra is undoubtedly a normal centre of sexual feeling, as Pouillet pointed out many years ago; a woman medical correspondent, also, writes that in some women the maximum of voluptuous sensation is at the vesical sphincter or orifice, though not always so limited. E. H. Smith, indeed, considers that "the urethra is the part in which the orgasm occurs," and remarks that in sexual excitement mucus always flows largely from the urethra.[[198]] It should be added that when once introduced the physiological mechanism of the bladder apparently causes the organ to tend to "swallow" the foreign object. Yet for every case in which the hair-pin disappears and is lost in the bladder, from carelessness or the oblivion of the sexual spasm, there must be a vast number of cases in which the instrument is used without any such unfortunate result. There is thus great significance in the frequency with which cases of hair-pin in the bladder are strewn through the medical literature of all countries.
In 1862, a German surgeon found the accident so common that he invented a special instrument for extracting hair-pins from the female bladder, as, indeed, Italian and French surgeons have also done. In France, Denucé, of Bordeaux, came to the conclusion that hair-pin in the bladder is the commonest result of masturbation as known to the surgeon. In England cases are constantly being recorded. Lawson Tait, stating that most cases of stone in the bladder in women are due to the introduction of a foreign body, very often a hair-pin, adds: "I have removed hair-pins encrusted with phosphates from ten different female bladders, and not one of the owners of these bladders would give any account of the incident."[[199]] Stokes, again, records that during four years he had four cases of hair-pin in the female urethra.[[200]] In New York one physician met with four cases in a short experience.[[201]] In Switzerland Professor Reverdin had a precisely similar experience.[[202]]
There is, however, another class of material objects, widely employed for producing physical auto-erotism, which in the nature of things never reaches the surgeon. I refer to the effects that, naturally or unnaturally, may be produced by many of the objects and implements of daily life that do not normally come in direct contact with the sexual organs. Children sometimes, even when scarcely more than infants, produce sexual excitement by friction against the corner of a chair or other piece of furniture, and women sometimes do the same.[[203]] Guttceit, in Russia, knew women who made a large knot in their chemises to rub against, and mentions a woman who would sit on her naked heel and rub it against her. Girls in France, I am informed, are fond of riding on the chevaux-de-bois, or hobby-horses, because of the sexual excitement thus aroused; and that the sexual emotions play a part in the fascination exerted by this form of amusement everywhere is indicated by the ecstatic faces of its devotees.[[204]] At the temples in some parts of Central India, I am told, swings are hung up in pairs, men and women swinging in these until sexually excited; during the months when the men in these districts have to be away from home the girls put up swings to console themselves for the loss of their husbands.
It is interesting to observe the very wide prevalence of swinging, often of a religious or magic character, and the evident sexual significance underlying it, although this is not always clearly brought out. Groos, discussing the frequency of swinging (Die Spiele der Menschen, p. 114) refers, for instance, to the custom of the Gilbert Islanders for a young man to swing a girl from a coco palm, and then to cling on and swing with her. In ancient Greece, women and grown-up girls were fond of see-saws and swings. The Athenians had, indeed, a swinging festival (Athenæus, Bk. XIV, Ch. X). Songs of a voluptuous character, we gather from Athenæus, were sung by the women at this festival. J. G. Frazer (The Golden Bough, vol. ii, note A, "Swinging as a Magical Rite") discusses the question, and brings forward instances in which men, or, especially, women swing. "The notion seems to be," he states, "that the ceremony promotes fertility, whether in the vegetable or in the animal kingdom; though why it should be supposed to do so, I confess myself unable to explain" (loc. cit., p. 450). The explanation seems, however, not far to seek, in view of the facts quoted above, and Frazer himself refers to the voluptuous character of the songs sometimes sung.
Even apart from actual swinging of the whole body, a swinging movement may suffice to arouse sexual excitement, and may,—at all events, in women,—constitute an essential part of methods of attaining solitary sexual gratification. Kiernan thus describes the habitual auto-erotic procedure of a young American woman: "The patient knelt before a chair, let her elbows drop on its seat, grasping the arms with a firm grip, then commenced a swinging, writhing motion, seeming to fix her pelvis, and moving her trunk and limbs. The muscles were rigid, the face took on a passionate expression; the features were contorted, the eyes rolled, the teeth were set, and the lips compressed, while the cheeks were purple. The condition bore a striking resemblance to the passional stage of grand hysteria. The reveling took only a moment to commence, but lasted a long time. Swaying induced a pleasurable sensation, accompanied with a feeling of suction upon the clitoris. Almost immediately after, a sensation of bursting, caused by discharge from the vulvo-vaginal glands, occurs, followed by a rapture prolonged for an indefinite time." The accompanying sexual imagery is so vivid as almost to become hallucinatory. (J. G. Kiernan, "Sex Transformation and Psychic Impotence," American Journal of Dermatology, vol. ix, No. 2.)
Somewhat similarly sensations of sexual character are sometimes experienced by boys when climbing up a pole. It is not even necessary that there should be direct external contact with the sexual organs, and Howe states that gymnastic swinging poles around which boys swing while supporting the whole weight on the hands, may suffice to produce sexual excitement.
Several writers have pointed out that riding, especially in women, may produce sexual excitement and orgasm.[[205]] It is well-known, also, that both in men and women the vibratory motion of a railway-train frequently produces a certain degree of sexual excitement, especially when sitting forward. Such excitement may remain latent and not become specifically sexual.[[206]] I am not aware that this quality of railway traveling has ever been fostered as a sexual perversion, but the sewing-machine has attracted considerable attention on account of its influence in exciting auto-erotic manifestations. The early type of sewing-machine, especially, was of very heavy character and involved much up and down movement of the legs; Langdon Down pointed out many years ago that this frequently produced great sexual erethism which led to masturbation.[[207]] According to one French authority, it is a well-recognized fact that to work a sewing-machine with the body in a certain position produces sexual excitement leading to the orgasm. The occurrence of the orgasm is indicated to the observer by the machine being worked for a few seconds with uncontrollable rapidity. This sound is said to be frequently heard in large French workrooms, and it is part of the duty of the superintendents of the rooms to make the girls sit properly.[[208]]
"During a visit which I once paid to a manufactory of military clothing," Pouillet writes, "I witnessed the following scene. In the midst of the uniform sound produced by some thirty sewing-machines, I suddenly heard one of the machines working with much more velocity than the others. I looked at the person who was working it, a brunette of 18 or 20. While she was automatically occupied with the trousers she was making on the machine, her face became animated, her mouth opened slightly, her nostrils dilated, her feet moved the pedals with constantly increasing rapidity. Soon I saw a convulsive look in her eyes, her eyelids were lowered, her face turned pale and was thrown backward; hands and legs stopped and became extended; a suffocated cry, followed by a long sigh, was lost in the noise of the workroom. The girl remained motionless a few seconds, drew out her handkerchief to wipe away the pearls of sweat from her forehead, and, after casting a timid and ashamed glance at her companions, resumed her work. The forewoman, who acted as my guide, having observed the direction of my gaze, took me up to the girl, who blushed, lowered her face, and murmured some incoherent words before the forewoman had opened her mouth, to advise her to sit fully on the chair, and not on its edge.
"As I was leaving, I heard another machine at another part of the room in accelerated movement. The forewoman smiled at me, and remarked that that was so frequent that it attracted no notice. It was specially observed, she told me, in the case of young work-girls, apprentices, and those who sat on the edge of their seats, thus much facilitating friction of the labia."
In cases where the sewing-machine does not lead to direct self-excitement it has been held, as by Fothergill,[[209]] to predispose to frequency of involuntary sexual orgasm during sleep, from the irritation set up by the movement of the feet in the sitting posture during the day. The essential movement in working the sewing-machine is the flexion and extension of the ankle, but the muscles of the thighs are used to maintain the feet firmly on the treadle, the thighs are held together, and there is a considerable degree of flexion or extension of the thighs on the trunk; by a special adjustment of the body, and sometimes perhaps merely in the presence of sexual hyperæsthesia, it is thus possible to act upon the sexual organs; but this is by no means a necessary result of using the sewing-machine, and inquiry of various women, with well-developed sexual feelings, who are accustomed to work the treadle, has not shown the presence of any tendency in this direction.
