While de Sade mentally explored a wide range of sexual deviations, his known behavior includes "only the beating of a housemaid and an orgy with several prostitutes—behavior significantly departing from the clinical definition of sadism".[7][8] De Sade was a proponent of free public brothels paid for by the state.
Despite having no legal charge brought against him,[7] De Sade was incarcerated in various prisons and an insane asylum for about 32 years of his life (or, after 1777, solely due to lettre de cachet and involuntary commitment): seven years in the Château de Vincennes, five years in the Bastille, a month in the Conciergerie, two years in a fortress, a year in Madelonnettes Convent, three years in Bicêtre Asylum, a year in Sainte-Pélagie Prison, and 12 years in the Charenton Asylum. During the French Revolution, he was an elected delegate to the National Convention. Many of his works were written in prison.

換句話說，你要理解，他的書寫，是獄中的書寫，是想像的書寫，是邊寫邊笑到，腰，和/或，老二，伸不直的的書寫，意思是說，從他的囚房，傳來歌劇般的叫床，這是有難度的，不信下次，你叫叫看，
