Monamour is a 2005 Italian erotic romance film directed by Tinto Brass and starring Anna Jimskaia.
Marta is a young Nymphomaniac housewife, married to a man named Dario, who works for a successful book publisher and is wealthy.
Despite loving her husband, Marta finds their sex life dull and predictable, having resorted to frequent masturbation to satisfy herself.
Later that night, while Dario is dressing for a party, Marta informs him of the assault, which he dismisses as a fantasy born of her dissatisfaction.
Marta insults Dario and tells him she enjoyed the encounter, at which point he jokingly dares her to go to the party without wearing any panties.
Sylvia reveals one of the two others she came to the party with is her secret lover, named François, and claims her husband has improved sexually since she had an affair with him.
Dario enters the hotel room, searching for documents he had forgotten, and finds Marta's journal which she had hidden in a drawer.
He reads it, learning of her dissatisfaction with their marriage and sex life, as well as the full details of her encounters with Leon, which at this point he had still believed to be fantasy.
Dario walks in on her writing, at which point he confronts her about his suspicions of her cheating, yelling at her, hitting her, and calling her a slut.
Marta wakes up alone, and finds a letter from Dario in which he apologizes for his actions and asks her to come to the closing party of the Festival with him.
At another party, Marta dances in front of Leon while a band plays, letting her breasts fall out of her dress and flashing several onlookers.
After the song she dances to ends, Marta and Leon have sex, while others avert their eyes or look confused and shocked.
