First published in 1917. The author was Chief of the Department of Genito-Urinary Diseases and Dermatology, Bronx Hospital. According to the Preface: "In the first chapter of this book I have shown, I believeconvincingly, why sex knowledge is even more important for women than it is for men. I have examined carefully the books that have been written for girls and women, and I know that it is not bias, nor carping criticism, but strict honesty that forces me to say that I have not found one satisfactory girl's or woman's sex book. There are some excellent books for girls and women on general hygiene; but on sex hygiene, on the general manifestations of the sex instinct, on sex ethics--none. I have attempted to write such a book. Whether I have succeeded--fully, partially or not at all--is not for me to say, though I have my suspicions. But this I know: in writing this book I have been strictly honest with myself, from first page to last."
