Secrets of a Door-to-Door Salesman (1973)

The saucy European sex comedy Secrets of a Door-to-Door Salesman (1973) asks in its tagline: "After all what's a woman to do when a handsome man rings her bell?" The question may be pointed, but it's no trick. David Clyde plays the titular peddler, whose day-to-day travels put him in direct contact with eager, horny ladies-of-various-houses who can't wait to welcome him in for a pitch session. Among the amorous customers are Sue Longhurst, Felicity Devonshire, and Victoria Burgoyne. These are secrets worth spilling.
