Cosi fan tutte ( All ladies do it )

Diana is happily married to Paolo but due to her wild passion for sex, she regularly winds up in short lived erotic adventures, which she doesn't keep hidden from Paolo. On the contrary: by telling him, their sexual relationship is fueled with fresh impulses. When Diana experiences a stormy affair with the poet Alphonse, Paolo gets jealous after all and rejects Diana, who then goes head first in to a wild orgy of sexual excess with her sister and some friends.
