Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. The multitudes of young men and young women who are ignorant of the perils to which their lack of sex training may expose them; the victims of wild oats sowing who are now reaping the frightful harvest in untold mental and physical agonies as a result of such ignorance; the millions of fathers and mothers whose criminal silence on this most important of all subjects may ruin the lives of the sons and daughters for whose happiness they would make any sacrifice; to my unknown friends scattered all over the world whom I have never met, but who, I feel, are one with me in the desire to give the world a lift for the things worth while, this little book is affectionately dedicated by The Author.
