This film ["Do Communists Have Better Sex"], a mixture of scholarly research and light-hearted presentations of stereotypes about the role of sex in divided Germany (from the end of the Second World War to the fall of the Berlin Wall), is a welcome addition to recent discussions of sexuality in East and West Germany...
...But where the director might have offered in-depth analyses of the private and public topic of sexuality and sexual mores, the insertion of numerous "humorous animation sequences"... throughout the film take the place of critical discussion, offering the viewer instead facile stereotypes that all too often leave one cringing in embarrassment. It will be difficult for some scholars or students to get beyond one of the first animated scenes, in which a doctor measures the penises of a West German man (16.9 cm) and an East German man (17.5 cm). No evidence in the film backs up such an absurd cartoonish claim...

Distantly though clearly related in a very essential, if conceptual way, see Young-Hae Chang Heavy Industries' masterpiece, titled Cunnilingus in North Korea, if you haven't already...
