Before The Joy of Sex
An ABZ of Love was a charming 60s book (originally in Danish) promoting a sane view of sex. It needed to say that “a masculine woman is not necessarily homosexual, and a homosexual woman is not necessarily masculine” and a few of the line drawings (sex positions, a man with an erection) were considered unfit to print in the original American edition. I enjoyed it at the time and like this retrospective look at it.
