All Ladies Do It (1992) on Netflix

Plot summary

Diana Bruni is twenty-four and has been married to Paolo for five years; the routine of their life together is no longer enough for her. An inexplicable restlessness pushes her toward other men, and she begins a series of short-lived erotic adventures. She hides none of it from Paolo: she describes the encounters to him herself in vivid detail, hoping the accounts will stir the desire between them. He listens as though she were inventing stories. Silvio, the owner of a lingerie shop, pursues her, and she resists his advances. Her friend Antonietta and her sister Nadia push her to go further.
