Married People, Single Sex (1994)

Various husbands, wives, friends, and lovers pair off in this erotic tableaux of sexual dysfunction. A frustrated construction worker turns to phone sex when his wife can't satisfy him; a topless dancer submits to the alluring "I do not know what" of one of her patrons; and a frustrated wife cheats on her by-the-book husband because she wants "the lust to be there."
