Unmentionable: the Victorian Lady's Guide to Sex, Marriage, and Manners / Therese Oneill, 307 pp.
Oneill invites her readers to time travel and experience day-to-day life as a(n upper-middle-class) Victorian woman. In chapters covering topics such as contraception, table manners, the toilet (or lack thereof), masturbation, menstruation, and, of course, sex, Oneill makes the point that life is better now, or at least less disgusting. Although many passages are laugh-out-loud funny, she's assembled a substantial amount of research. Fun photos with silly captions round this out. Quick and fun.
