Dangerous Sexualities takes a look at how our ideas of health and disease are linked to moral and immoral notions of sex. Beginning in the 1830s, Frank Mort relates his social historical narratives to the sexual choices and possibilities facing us now. This long-awaited second edition has been thoroughly updated to include new discussions of eugenics, race hygiene and social imperialism in the late nineteenth and early twentieth centuries. With a new and extended bibliography, introduction and illustrations, this second edition brings a classic into the 21st Century.
