SANE SEX LIFE AND SANE SEX LIVING SOME THINGS THAT ALL SANE PEOPLE OUGHT TO KNOW ABOUT SEX NATURE AND SEX FUNCTIONING; ITS PLACE IN THE ECONOMY OF LIFE, ITS PROPER TRAINING AND RIGHTEOUS EXERCISE H.W. LONG, M.D. _AUTHORIZED EDITION_ EUGENICS PUBLISHING CO., INC. NEW YORK 1919 MADE IN THE UNITED STATES OF AMERICA TO MY FELLOW-MEMBERS OF THE MEDICAL PROFESSION INTO WHOSE HANDS THIS BOOK MAY COME, AND TO ALL WHO MAY READ IT UNDER THEIR DIRECTION, THIS VOLUME IS MOST SINCERELY DEDICATED BY THE AUTHOR. NOTE TO THE READER IN ORDER TO GAIN A CORRECT IMPRESSION OF THE BOOK, IT IS ESSENTIAL THAT IT BE READ FROM THE BEGINNING TO THE END WITHOUT ANY SKIPPING WHATSOEVER. ONCE READ, IT CAN BE RE-READ, HERE AND THERE, AS THE READER MAY DESIRE. BUT FOR A FIRST READING, IT IS THE EARNEST WISH OF THE AUTHOR THAT EVERY WORD BE READ, FOR IN NO OTHER WAY CAN THE PURPOSE OF THE BOOK BE REALIZED. INTRODUCTION As we have moved down the ages, now and then, from the religious teacher, the statesman, the inventor, the social worker, or from the doctor, surgeon, or sexologist, there has been a "_vox clamantis in deserto_." Usually these voices have fallen on unheeding ears; but again and again some delver in books, some student of men, some inspired, self-effacing, or altruistic one has taken up the cry; and at last unthinking, unheeding, superficial, self-satisfied humanity has turned to listen. Aristotle by the sure inductive method learned and taught much, concerning the sex relations of men and women, that it would profit us today to heed. Balzac, Luther, Michelet, Spencer, and later, at our very doors, Krafft-Ebbing, Forel, Bloch, Ellis, Freud, Hall, and scores of others have added their voices. All these have seen whither we were drifting, and have made vigorous protests according to their lights. Many of these protests should have been heard, but were not, and only now are just beginning to be heeded. Such pioneers in the field of proper, healthful, ethical, religious, sane daily sex living, have been Sturgis and Malchow, who talked earnestly to an unheeding profession of these things, and now, I have the honor to write an introductory word to a book in this field, that is sane, wise, practical, entirely truthful, and unspeakably necessary.
