Story the Soldiers Wouldn't Tell: Sex in the Civil War by Thomas P. Lowry M.D.
The men in blue and gray had a secret life, one that they and their families tried to hide from posterity. In the American Civil War, apparently there was no sex. But of course there was, and Dr. Thomas P. Lowry reveals this hidden dimension of the lives of Johnny Reb and Billy Yank, lives that included pornographic books and photographs, bawdy songs and dirty jokes, prostitution (sometimes legalized), homosexuality, and rape. Frequently ribald, often hilarious, this book is nonetheless a very serious study of Civil War soldiers and their attitudes on a subject just as constantly on their minds as on our own.
