I jomfruens tegn AKA In the Sign of the Virgin (1973) - Finn Karlsson

The impending approach of Venus, known to cause "disturbing erotic behavior", sends two men with very different missions to the town of Petit-Bois, one to save the schoolgirls from lust, the other to test a new aphrodisiac. Of course, chaos ensues.

This is the first Danish zodiac erotic comedy of six. It is very much in the same bawdy and politically incorrect spirit as the Danish erotic bedside comedies from that same era of the 1970s.

Starring: Ole Søltoft, Sigrid Horne-Rasmussen, Bent Warburg, Lone Gersel, Anne Bie Warburg, Vivi Rau, Doris Klemens, Faith Thrue, Ditte Maria, Eva Lindberg, Susan Skog, Mette Egholm, Leni Kjellander, Lone Helmer & Benny Hansen.

IMDb review:

I was exceedingly happy to be able to find this old gem. In the early 70s, there was brief window when porn was where many cinematic experiments were happening. Some of them actually had some promise for being important. Perhaps the oddest is the porn musical. This is the most interesting from a historical perspective.

You have to place yourself in the era: a huge percentage of the population believed that the world was in a time of change for the better and this change had something to do with the overlap of free sex, drugs, some astrological appropriateness and the end of war. At the same time, the American government was hammering back on all fronts, while the Dutch and Danish governments were seemingly alone in supporting all four.
