In La Sculacciata (1974), a feisty young couple watches their marriage hit the skids when the husband grows mysteriously impotent. Antonio Salines stars as the male hero of this pre-Viagra tale, in which his eager lover Elena (Sydne Rome) grows desperate for the satisfaction she’s grown comfortably accustomed to. Aching to return to their days of blissful ecstasy, Elena pulls out all the stops, treating her limp hubby to all manner of sexy lingerie, enticing positions, and kinky suggestions. Rome rises to this particular acting challenge with a bravura performance that will have able-bodied men everywhere salivating.
