Times have changed! Women are no longer off with the unimaginativeness of men. Sex machines are just as frowned upon as limp softies. Sex is no longer talked about behind closed doors.

A teenage couple provides sexual information for their peers in words and pictures, combining their ideological criticism of the older generation with a call for sexual liberation.

Sex education film made by Dietrich Krausser.
