While X-rated cartoons were not an unknown commodity when this film was released in 1974 (Fritz the Cat had been around since 1972), animation which has a clearly pornographic intent was (and remains) a novelty. This film features voices by two former members of The Turtles and later of The Mothers of Invention, Mark Volman and Howard Kaylan. The story involves a shy man who has not been able to figure out what sex is actually about until he meets a large-breasted duck(!).
