Oswalt Kolle played a significant role in the sexual revolution in Germany.
Of all sexual revolutions (see here), the one that occurred in the 1960s was the most pervasive, due to mass media, the pill and general economic prosperity.
It was a funny revolution. A friend once told me that it was just an excuse for all alpha males to bang as many women as they could get their hands on. This is an exaggeration, of course, but contains some truth.
It was the start of sex education in state schools, like the Sexualkundeatlas of 1969, but also of state-funded sexual education films Helga – Vom Werden des menschlichen Lebens.
