What metaphors are used in The Bedroom Philosophers by Marquis de Sade?

The boudoir is the setting for five of the seven dialogues in The Bedroom Philosophers. It is a metaphor for psychological and sexual dynamics. It belongs to Madame de Saint-Ange and serves as a staging area for the many sexual couplings and libertine lessons of the narrative. When Madame de Saint-Ange enters the boudoir with Eugenie, Dolmance is waiting there for them. Later, the Chevalier de MIrvel and the servant Augustin join them. At the end of the book, Madame de Mistival barges into the boudoir, where she is abused by the libertines.
