The Swinger (1966)

The sex comedy The Swinger (1966) stars Ann-Margret as a mild-mannered journalist who poses as a swinger in order to convince the macho Hefner-esque editor of “Girl-lure” magazine to publish her article about the swingers’ scene instead of asking her to pose as a centerfold. There’s no skin here, but you’ll be swinging with yourself when you see Ann-Margret in a leopard-print bikini.
