Pierre Chevalier – Hommes de joie pour femmes vicieuses (1974)
This is sex comedy from the prolific Eurocine studio, who produced many sex, horror and thriller exploitation films throughout the 70s, including stuff from Jean Rollin and Jess Franco. This one is by Pierre Chevalier, who also made Orloff and the Invisible Man, among many others.
This was recorded from TV to VHS and subsequently transferred to DVDr, so the quality is not great, but the film appears to be quite rare. English dub.
