Looking for Porn Segment(actual porn)

Feel free to suggest a better forum for this, but here we go: WHen I was way too young I used to watch over and over, 4 VHS cassettes with recorded tv-porn..
One segment stood out: A documentary-style segment about a popular vacation-island, where "Sex demons" had become a problem(lol). It was not a "silly" fake documentary, but it looked very serious. We se a short interview with some old academic And we also get to see a frustrated couple who gets disturbed by Orgies showing up, from thin air. Even though they call them demons, they look and behave like normal people.

I didn't recognize any of the many actors in that segment. All other segments had At least one very famous face. But the spoken Language was English, and the narrator was female.
