Before closing this subject, however, I want to tell of a case of an eight year old boy I attended during an attack of measles. I found he was shy and unresponsive, and at times very nervous and irritable with a strong liking to be alone. I observed him closely for a few days and reported the results of my observation to the attending physician. He was convinced of the truth, that the little fellow was masturbating. The physician assigned me to the task of talking to the child, who acknowledged that he was “touching” himself and had been ever since he could remember. The little fellow's mother had died when he was in infancy, leaving beside himself a brother a year older with whom he slept. I explained to him the danger as well as I could and the result was that I was awakened in the night by whisperings and found the little fellow asking the older brother to tie his hands to the bedpost. This the older brother did with a handkerchief, and the child went to sleep in this way every night during the few weeks I was attending him. The first few nights he was awake practically all of the time struggling to overcome this habit, which he finally overcame completely. At puberty every boy and girl should be taught these dangers and temptations and also how to avoid them, by keeping active, mentally and physically, going to bed only when sleepy, avoiding intoxicating drinks and stimulants. We have strayed some distance, I know, from the beginning of our subject—Sexual Impulse—to treat of its perversion (masturbation), but we shall now take up the normal natural impulse and see what there is that every girl should know. SEXUAL IMPULSE—PART II. In the first part of this article we learned that the sexual impulse is a combination of the two impulses: the one which impels the discharge of ripe sex cells, strongest in the boy, and the other which impels the individual to touch or caress an individual of the opposite sex, strongest in the girl. Every girl has in mind an ideal man. This ideal begins to form sometime in the early adolescent age. He is usually distinct in her mind as to his physical qualities, such as dark or light hair, or brown or blue eyes. He is always a certain physical type and often remains an ideal to her through life. At the forming period of the type she will be attracted toward many men who seem to answer the ideal type, but as she reads and develops through the various stages of the adolescent period, the ideal changes and grows with her. As she reaches the romantic stage the ideal must be brave, daring, courteous. If she is inclined toward outdoor sports he must be athletic. And so it goes on until the twenty-third year, when the average girl has a fairly settled idea of the man who would suit her as a mate through life.
