Werner M. Lenz – Oswalt Kolle: Dein Kind, das unbekannte Wesen aka Your Child, That Unknown Creature (1970)
This is a continuation of the sex education films by Oswald Kolle. The entire Kolle family appears nude and openly discusses sex among the parents, two daughters and one son. The father recommends masturbation for children unless the act would be traumatic for the participant. Some mention of the Oedipal complex is discussed, but no details are given because individual situations may vary. The color process is not credited. ~ Dan Pavlides, Rovi
Short review from Rare Film Finder:
An excellent documentary by German sexuality expert, Oswalt Kolle.
The programme does not shy away from the subject and features frank and open discussion with Kolle, his wife, his teenage son and daughter, and his 4-year-old son. Most of the discussion takes place on a German naturist beach where the whole family are, naturally, in the nude.
