Nessuno è perfetto (1981)

Guerrino falls in love with Chantal (Ornella Muti), a model who used to be a man, a former German army paratrooper who had a sex change. Without knowing about his past, Guerrino would like to have a son, with constant refusals from Chantal. The man investigates and discovers the truth. After an initial shock, the couple decides to stay together despite criticism from friends.
In the thirty-ninth minute Ornella Muti walks in a meadow with a man, hand in hand. She wears a tight pink tank top with nothing underneath. Nipples are visible under the fabric. In the sixtieth minute Ornella is sleeping wearing black lingerie. A man enters her room and lifts the sheet, showing us the actress in all her beauty. At the eighty-eighth minute a man removes Ornella’s skirt, who is left in a semi-transparent leotard. In the next scene, Ornella Muti naked is having sex with a man, he lying on the bed, she on top of him.
