In the proper understanding of this subject of sex hygiene it is quite impossible for either men or women to go very far alone. I am sure that through the ages there have been men who have had this subject very close to their hearts. They have felt that it was basic, that it was most important; but they felt that it was not a proper matter to discuss with women and so they have blundered on, not getting very far in any solution of it. The subject has also been near the heart of every woman. She hopes that her husband will be a good man; she hopes that her son will be clean; she sees all the wreckage and the heartaches in life that come from ignorance of sex hygiene or lack of attention to it. So women have talked together as to how the standard of morality might be raised, how they might teach their sons and daughters, but they have felt that it was not a topic to discuss with men, so they have blundered on. They have been too sentimental, they have been too ignorant of the limitations in the world of practical affairs; they have lacked well-balanced judgment as to how it was best to teach, how it was best to help. It is absolutely necessary that earnest men and women should modify and guide each other in reaching a solution of the problem. No home can be successful in its teaching of this subject unless the father and mother agree on the teaching; if the father thinks it is not a subject for his wife to consider or to talk about, or if the mother imagines that she alone shall tell her child, those children will grow up with a feeling that there is discord at the root of the family feeling on a most vital subject. Whether the father or mother shall tell the child is very immaterial. The opportunity may come to one, it may come to the other; both should be ready to meet it when it does come.
