Your Child, That Unknown Creature (Dein Kind, das unbekannte Wesen) 52 years old
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.
