Masturbation is further found among peoples of nearly every race, however natural the conditions are under which men and women live. Masturbation was known among all races at every period of history. It is reported that the great Cynic Diogenes practised autoeroticism publicly in his tub. Schools, academies, educational institutions, dormitories of colleges, factories or prisons are hot-beds of masturbation. Prof. Schiller published the observations in a certain gymnasium (collegiate high school) where the boys had holes in the pockets of their trousers ad stuprum mutuum faciendum during the lessons, in the presence of their professors. Thomalla knows of a boarding school where bets are made among the boys on the skill of their exercitatio stuprosa. The boy who can induce the ejectio seminis the quickest receives the prize. Walter Benseman (Public School and Gymnasium) describes the most deplorable conditions existing in a great many boarding schools in England. In France, Deville and Tarnowsky found the spread of masturbation in schools, colleges and pensionates to be enormous. Male masturbation, as a rule, is effected by fricando glandem manu. Hence such mishaps, as often happen in woman, are of rare occurrence. Still many queer objects were found in the male urethra or bladder, such as quills, pencils, penholders, blades of straw, knitting needles, pieces of bougies or of catheters, ear-spoons, tooth-picks, all introduced for masturbating purposes. Senn removed in a young man, nineteen years of age, a stem of a plant from the bladder, which was introduced into the bladder for autoerotic purposes. The author removed a pencil from the pars membranacea of a boy of eighteen, through an incision in this part. Such cases are exceedingly rare in the male. As a rule, autoeroticism in men is accomplished by the hand alone, hence the name “masturbation.” In some cases neither the hand nor any other means is needed to obtain the desired end. The fancy of concarnatio alone will produce the orgasm, as in the following case, told the author in confidence: A young man, twenty years of age, while sitting behind an attractive young lady in theatre, was in the habit of allowing his fancy free rein by imagining himself of being in complexu venereo with his fair neighbor. This thought alone sufficed to induce ejaculation and orgasm. One Sunday while sitting near a fair worshipper in church, he got so excited that he had to practise ideal congressum cum ea during the sermon.
