Excerpt from Rational Sex Ethics: A Physiological and Psychological Study of the Sex Lives of Normal Men and Women, With Suggestions for a Rational Sex Hygiene With Reference to Actual Case Histories I have received many valuable suggestions for this study, and much really serviceable help has been rendered me by many educated, altruistic men and women. Nay, but for their voluntary contributions of secrets long held inviolate in the soul's innermost recesses, this study and anything of value that may arise from it, would not have been possible. I desire at this time to express my deepest thanks and highest appreciation for what I know was, to all these, not only a sacrifice of valuable time, but of carefully guarded feelings. Because of the large number, and for other obvious reasons, I am not able to name those to whom I am indebted, but I trust that the proper parties, one and all, will feel that I am none the less grateful; and I am sure that they will know that my earnest hope unites with theirs that these personal sacrifices may be of some value to the present and rising generations.
