Is this the original title? The title screen has a very different font from the opening credits and a slightly different font from the closing credits.

After the opening screen (All Star presenta) there is a screen saying, among other things, that the film was performed by non-professional actors and actresses. If this is true then the they were making their debuts. And if you believe that...

There are five female names in the credits, but six female performers. Thanks to JohRay 1 and marcel_43 for identifying some 'unknowns'.

Male names in the credits (also possibly incomplete) are Gunter Geofry, Mario Lisi, Federico Manna and Pierluigi Gori.

Males identified: Porno-Ralle aka Ralf Dorman and Paul Gregorius. (Thanks to Igwin for the IDs).
