A young lady of twenty-five prefers to ride in crowded street cars and, if possible, refuses to accept a seat when offered by a sympathetic man, but remains standing before him, holding on to the strap. She then indulges in ideal auto-erethism by fancying herself of being in concarnatione viri ante se sedentis, cujus genua tentat quam sæpessime tangere suis genibus. At one occasion while riding in a crowded car and standing before a man who was interested in reading a book, pressit suis genibus viri genu during the orgasm in such a way that the man, a physician, looked up to see what was going on. The glowing face was in a state of extreme excitement. The staring eyes were fixed on one point, the hands holding the strap were trembling. Respiration was panting and the countenance distorted to a veritable grimace. With some women even lustful thoughts are not required to induce sexual libido. They are found among women who are the victims of sexual repression. They restrain themselves from attaining orgasm in the natural way for moral or social reasons. Occasionally the internal stimuli overmaster them and bring about a sexual paroxysm, in the absence of any external stimulus and without resorting to ideal congressus. Sérieux records the case of a woman, fifty years of age, who lived a chaste life. At times violent crises of sexual paroxysms would come on without any accompaniment of voluptuous thoughts or any mechanical help. In some patients orgasm may be induced by means of sensory impressions, as by listening to music or the sight of nature in the country, and by the taste and touch of things which have no bearing upon the sexual parts whatever. Schrenk-Notzing records the case of a female masturbator who induced orgasm without any tactile manipulation, simply by listening to music or while regarding paintings that displayed nothing of a lascivious character. Another of his patients became sexually excited by the sight of the grandeur of nature, as by the sea, or high mountains. With another of his patients the mere sight of a specially strong and sympathetic man immediately brings on orgasm. In Ellis’ case the patient, while still a young girl, whenever a certain artist, whom she admired, touched her hand, felt erections and moisture in muliebribus. When her uncle’s knee once accidentally came in contact with her thigh, ejaculation took place. Once, casually seeing virilia, a convulsive ejaculation occurred accompanied by a delightful sensation, every fibre tingling with an exquisite glow of warmth. One of the author’s hysterical patients became greatly excited sexually whenever she ate liver-sausages.
