The Sex Side of Life: An Explanation for Young People 

The Sex Side of Life is a sex education pamphlet written by Mary Ware Dennett with a goal to educate her sons, because she was unable to find any adequate books on the subject. Many of the books on sex either contained inaccurate information or used fear and shame tactics to dissuade the youth from having sex. Therefore, she decided to write her own explanation using research and interviews with doctors. The pamphlet was twenty-four pages long. Dennett used scientific discussion of sex while also including the emotion side of sex relations. The pamphlet covered controversial topics including masturbation, sexually transmitted diseases, prostitution, and support for the use of birth control. Her views were considered radical for this time, because she was not promoting abstinence.
