Lesbian exposé / Alan Metcalfe.

"Nowadays lesbianism is far more widespread than is generally thought. In fact, there are about 25 million in the world, many of whom are married and bisexual. It occurs between all creeds and classes of women, from every social position. Although there are no figures available as to the percentage of women engaging in erotic practices with their own sex, female homosexuality seems to be on the somewhat rapid increase."--Provided by publisher.
