有声读物: Unmasked, or the Science of Immorality. To Gentlemen

Mary Edwards Walker was a physician and surgeon who served in the Civil War. An abolitionist, prohibitionist, and cross-dressing leader of the women's dress reform movement, she published this lively sex manual in 1878. It is a curious blend of useful information and Victorian sexual mythology, at once puritanical and explicit. (Summary by Pamela Nagami)
