Completed in 1922, this book is a fascinating window to sex and sexuality in the 1920s. It explores a (heterosexual) couple's relationship to sex throughout their lives, and offers advice on understanding your own body, pleasuring your partner, dealing with the practicalities of sex, and maintaining your sex life. 

The eugenics movement was a social and scientific effort that began in the late 19th century, aiming to improve the genetic quality of the human population through selective breeding and sterilization of those deemed "unfit." It gained significant traction in the early 20th century, particularly in the United States, but was discredited after World War II due to its association with Nazi atrocities and its flawed scientific basis.
