Sex is overemphasized by our civilization on its distracting side, its spicy and condimental values, and underemphasized so far as its realities go. The aim seems to be to titillate sex feeling constantly, and a precocious acquaintance with this form of stimulation is the lot of most city children. Such things would have no serious results to the housewife if they did not arouse expectations that marriage does not fulfill at all. This is the great harm of prurient clothes, literature, art, and stage,--it unfits people for sex reality. In how far the delayed marriages of men and women are good or bad it is almost impossible to decide. That unchastity increases with delay is a certainty, that fewer children are born is without doubt. Whether the fixation of habit makes it harder for the wife to settle down to the household, and the man less domestic, cannot be answered with yes or no. There seems to be no greater wisdom of choice shown in mature than in early marriages, though this would be best answered by an analysis of divorce records. That contraceptive measures have come to stay; that they are increasing in use, the declining birth rate absolutely evidences. I take no stock in the belief that education reduces fertility through some biological effect; where it reduces fertility it does so through a knowledge of cause, effect, and prevention. Some day it will come to pass that contraceptive measures will be legal, in view of the fact that our jurists and law makers are showing a decline in the size of their own families. When that time comes the discussion of means of this kind consistent with nervous health will be frank, and some part of the neurasthenia of our modern times will disappear. The vaster racial problems that will arise are not material for discussion in this book. Though not perhaps completely relevant to the nervousness of the housewife, it is not without some point to touch on the "neurosis of the engaged." The freedom of the engaged couple is part of the emancipation of youth in our time. Frankly, a love-making ensues that stops just short of the ultimate relationship, an excitement and a tension are aroused and perpetuated through the frequent and protracted meetings. Sweet as this period of life is, in many cases it brings about a mild exhaustion, and in other cases, relatively few, a severe neurosis. On the whole the engagement period of the average American couple is not a good preparation for matrimony. How to bring about restraint without interfering with normal love-making is not an easy decision to make. But it would be possible to introduce into the teaching of hygiene the necessity of moderation in the engaged period; it would be especially of service to those whose engagement must be prolonged to be advised concerning the matter. Here is a place for the parents, the family friend, or the family physician.
