Woman by William J. Robinson In the first chapter of this book I have shown, I believe convincingly, 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.
