Love Junkie - Robert Plunket

Mimi Smithers, bored aesthete manquée, lives with her husband Boyce in the New York suburbs, where dreams of dazzling social success elude her. Life takes a quite unexpected turn when she meets Joel, a stunningly handsome porn star. Soon she tumbles down the rabbit hole of Manhattan and Fire Island society, helping Joel with his lucrative mail order business (signed photographs, used underwear, 'verbal abuse audiotapes'), and her real adventures begin.
