Originally published in London 1933, this book is a concise introduction to sexual psychology primarily intended for medical readers and students but also aimed at a wider audience with its expert guidance and advice on numerous sexual topics. Contents include: Biology of Sex; Sexual Impulse in Youth; Sexual Deviation; Erotic Symbolisms; Homosexuality; Marriage; The Art of Love. etc. Many of these earliest books, particularly those dating back to the 1900s and before, are now extremely scarce and increasingly expensive.
