Sexual sadism, known as sadism (sm) in the west, refers to the consciousness and behavior related to sadism and abuse. In China, sm has a gentler name: Sadism. SadoMasochism, a word in English, is a combination of Sadism and Masochism. Its abbreviation is what we usually call SM. Sadism was first discovered at the end of 17, and first appeared in literary activities and some commercial abuse services. Of course, the earliest sadomasochi literature was the first to introduce the works of French writer Thad and Austrian writer Masoch, and the word sadomasochi was created by psychologist Richard von Krafft-Ebing through their names.
