One of the great discoveries of their work is that women can experience multiple orgasms. These were revolutionary ideas for their time. However, a recent study focusing on women and sex may surprise even Masters and Johnson. This is what Dr. Eden Fromberg and Naomi Wolffs come to in their new book, Vagina: A New Biography.
