Sex and the Emperor (1994)

Wong Jing produces and Sherman Wong Ching-wah directs this outrageous and occasionally grisly period sex flick set in the Forbidden City during the Qing dynasty. Neophyte eunuch Li Lianying, who, thanks to a bribe from his parents was spared one of his testicles, quickly learns that the Forbidden City is filled with petty sexually frustrated eunuchs and thousands of beautiful though equally sexually frustrated concubines. While Li has an affair with one such woman, he befriends the emperor, which calls down the jealous wrath of head eunuch Little One. In revenge, he tortures the emperor’s favorite, a maid named Guilian and casts her out into a cut-rate brothel. In response, the emperor goes into an insane sexual frenzy.
