This movie deals with a sexual behavior called "Candaulism", according to which the partner pulls his pleasure from exposing part or all of his wife's body. Not to be confused with "Cuckolding" ,in which the partner is seeking for humiliation. The psychological explanation comes from the fact that the partner identifies his wife's body as his own body, by showing her he shows his own body. On Xhamster it is expressed by posting Ex or GFs pics,or asking for comments or tributes from other men. Notice how the director Pasquale Festa Campanile recalls one of the most famous Man Ray's photography "Le Violon d'Ingres" in some of Laura Antonelli's poses.
