Teachers especially should be alive to the excessive danger of the so-called platonic attachments among their pupils. The sentimental fancy taken by an older boy to a younger boy in boys’ schools, or by an older girl to a younger girl, in girls' schools, between whom, in the regular course in the school, there ought to be very little natural companionship, is always suspicious. The teacher or guardian must know that such attachments, which appear so touching and romantic, have a most dangerous resemblance to abnormal passion. The sequelae of immoderate masturbation are often quite disastrous. There is, in the first place, general neurasthenia, with all its accompanying symptoms, as photopsias, glistening and dazzling before the eyes, photophobias, dry conjunctivitis (particularly found among masturbating young girls and old maids), and functional sexual disturbances, as diurnal pollutions and spermatorrhoea. Other symptoms are indolence, lack of energy, shyness in demeanor, want of self-reliance, disinclination to study, incapacity for serious work, shortness of memory, absent-mindedness, unsteadiness of character, hypochondria and melancholia. The children become peevish and irritable, they are reserved in conversation, apathetic in manner, hesitating in actions, slovenly in dress, and contradictory. Cerebral anemia is of common occurrence among those addicted to excesses in masturbation. Hence vertigo is a common symptom and fainting spells occur often. (Girls especially are liable to be affected by syncope.) Perspiration breaks forth on the slightest exertion, and the slightest exercise occasions much shortness of breath. Neuralgia of the testicles, ovaries and the bladder is also frequently caused by excess. The neuralgia of the neck of the bladder is particularly distressing. The patient is frequently seized with a desire to pass water, and the evacuation of the bladder is attended with pain. The frequent calls to urinate occur oftener during the day than during the night. Particular danger of long-continued masturbation lies in the development of impotency in men and frigidity in women. Besides the nervous phenomena, there are often found real anatomical alterations. As the habit is more frequently indulged in, the prolonged congestion produces a catarrhal process in the urethra, prostatic gland, seminal vesicles and varicocele[BP] in the male; and in the female, catarrh of the ovaries, tubes, uterus and especially of the endometrium. These conditions give rise to uncomfortable and distressing sensations which demand relief and are gotten rid of only by a continuation of the habit. Thus a vicious circle is continually at work. The results are stricture of the urethra, spermatorrhoea, disturbances of the intestinal tract, as dyspepsia, flatulence and constipation, and palpitation of the heart.
