Cinsiyet ve üreme, canlı yaşamının sürekliliğini sağlar. İnsanlarda cinsellik doğumla başlar ve tüm yaşam boyunca devam eder. Cinsel kimlik, kişinin biyolojik cinsiyetinden farklı olarak kendisini kadın ya da erkek olarak algılamasıdır. Sağlıklı bir cinsel kimlik gelişiminde cinsel kimlik, kişinin cinsiyetinden haberdar olması, cinsiyetine uygun davranışlar göstermesi ve bundan mutluluk duyması önemlidir.

Cinsel eğitim bireyin fiziksel, duygusal ve cinsel gelişimini anlaması olumlu bir kişilik kavramı geliştirmesi, insan cinselliğine, başkalarının haklarına, görüş ve davranışlarına saygılı bir bakış açısı edinmesi ve olumlu davranış biçimi, değer yargıları geliştirmesi eğitimidir.

Cinsel eğitimde öncelikle anne babaların eğitimi hedeflenmelidir. Aksi takdirde anne babaların istemediği takdirde çocuklar ya da ergenler istemediği kişilerden bilgi edinebilir, gözetleme, takip etme yoluna başvurabilirler, yaşıtlarından bilgi alabilirler, kendi başlarına deneyler yapabilirler. Ailede başlayan cinsel eğitim okulda da sistemli bir şekilde sürmelidir.

Ülkemiz gibi cinsel eğitim konusuna tedirgin, çekingen, korkak yaklaşılan, ayıp günah sayılan ülkelerde bu sorumluluk daha da artmaktadır. Sorumluluğun kapsamında sadece çocuklar gençler değil her yaştan her sosyo-ekonomik ve sosyo-kültürel düzeyden insanların olması gerekmektedir. Bu kitabın anne babalara öğretmenlere öğretmen adaylarına ve konuyla ilgilenen herkese yararlı olması dilerim.

The school is a product of civilization. It became necessary because of the division of labor caused by the multiplication of the interests of mankind which made it impossible for the home to continue wholly to care for the training of its children. The history of education must not merely treat of the development of the school, but it must consider education in its broader meaning; that is, as a history of civilization. For this reason some of the great educators of the world who have not been school teachers, must receive consideration.

Although the month is March and not November, it is never unseasonable to count up the blessings for which it is well to be thankful. In fact, from the standpoint of education, the spring is perhaps the appropriate time to perform this very pleasant function. As if still further to emphasize the fact that education, like civilization, is an artificial thing, we have reversed the operations of Mother Nature: we sow our seed in the fall and cultivate our crops during the winter and reap our harvests in the spring. I may be pardoned, therefore, for making the theme of my discussion a brief review of the elements of growth and victory for which the educator of to-day may justly be grateful, with, perhaps, a few suggestions of what the next few years may reasonably be expected to bring forth.

And this course is all the more necessary because, I believe, the teaching profession is unduly prone to pessimism. One might think at first glance that the contrary would be true. We are surrounded on every side by youth. Youth is the material with which we constantly deal. Youth is buoyant, hopeful, exuberant; and yet, with this material constantly surrounding us, we frequently find the task wearisome and apparently hopeless. The reason is not far to seek. Youth is not only buoyant, it is unsophisticated, it is inexperienced, in many important particulars it is crude. Some of its tastes must necessarily, in our judgment, hark back to the primitive, to the barbaric. Ours is continually the task to civilize, to sophisticate, to refine this raw material. But, unfortunately for us, the effort that we put forth does not always bring results that we can see and weigh and measure. The hopefulness of our material is overshadowed not infrequently by its crudeness. We take each generation as it comes to us. We strive to lift it to the plane that civilized society has reached. We do our best and pass it on, mindful of the many inadequacies, perhaps of the many failures, in our work. We turn to the new generation that takes its place. We hope for better materials, but we find no improvement.
