which later are concomitants of sexual union. Such, in brief, is the physiological history of the normal adolescent boy, and one who has fallen into even most limited masturbation will probably be still more conscious of the fact that the ordinary sequence of events in the activity of the sexual organs leads to intense excitement that has almost irresistible attractiveness. [Sidenote: Average young women different.] Now, most scientifically-trained women seem to agree that there are no corresponding phenomena in the early pubertal life of the normal young woman who has good health. A limited number of mature women, some of them physicians, report having experienced in the pubertal years localized tumescence and other disturbances which made them definitely conscious of sexual instincts. However, it should be noted that most of these are known to have had a personal history including one or more such abnormalities as dysmenorrhea, uterine displacement, pathological ovaries, leucorrhea, tuberculosis, masturbation, neurasthenia, nymphomania, or other disturbances which are sufficient to account for local sexual stimulation. In short, such women are not normal. Such facts have led many physicians to the generalization that the average healthy adolescent girl does not undergo normal spontaneous changes which make her definitely conscious of the nature, source, and desirability of localized sexual pleasure. On the contrary, such consciousness commonly comes to many only as the result of stimuli arising in connection with affection.[18] Clearly it is nonsense to claim that the sexual temptations arising within the individual are equal for the two sexes. Potentially, girls may have passions as strong as boys, but they do not become so definitely and spontaneously conscious of their latent instincts. [Sidenote: Helping the young man.] Thus considering the available facts regarding the physiological reasons for the sexual tendencies of men, it seems to me that we gain nothing in trying to minimize the young man's sexual problems, for he is quite conscious that they are insistent. Far better it is that mature men who know life in its completeness should make the young man feel that his problems are not new, not insignificant, and that many another man has met and solved them in such a way as to make life more full of real happiness. Such sympathetic helpfulness will mean something to a young man, but he cannot be led far by one who in his own early experience has not learned both the strength and the mastery of the sexual instincts.
