At another occasion, as house-physician in a European surgical clinic, the author assisted in the removal of a hair-pin from the bladder of a young woman, which was used to produce a tickling sensation of the clitoris, and which accidentally slipped into the urethra, and then entered the bladder. Other objects removed by surgeons are pencils, bodkins, knitting-needles, crochet-needles, penholders, quills, etc. Some women produce sexual excitement by frictions against the corner of a chair, table, etc. Morris relates of a lady, a devout church member, who never had allowed herself to entertain any sexual thoughts referring to men. Tamen se stuprabat every morning while standing before the mirror by rubbing against a key in the bureau drawer. One of the most common means to produce voluptificam titillationem, that is even found in use by children, when scarcely more than infants, is the voluntary pressure of the thighs. They are placed together and firmly crossed while the pelvis is rocked, so that the sexual organs are pressed against the inner and posterior parts of the thighs. Townsend records five cases of thigh friction in children less than one year old. The manipulation of the sewing machine with the body on the edge of the seat is sometimes used by young women as a means to produce sexual excitement, leading to orgasm. Horseback riding is sometimes employed as a means for inducing orgasm and ejaculation in women. The stimulation caused by bicycle riding is not seldom prolonged by women until orgasm is induced. Besides masturbation by means of tactile excitation, ideal auto-erethism is widely spread among women. The votaries induce sexual libido by means of lustful conceptions and thoughts. The mere thought concubitus induces orgasm and ejaculation in such women. Such women are able to practice auto-erethism at all times and in all places. While riding in crowded cars and upon the most serious occasions, in churches and in other sacred places, the mere libidinous thought of being in concarnatione induces orgasm. These voluptuous dreamers may stuprare without any visible manipulations while conversing with their friends or listening to a sermon.
