S is an abuser, which is difficult and requires good judgment, creativity and interest. Produce pleasure in the process of sadism

M is a masochist, which is less difficult and needs a certain degree of acceptance. Usually in S's sadomasochism, he enjoys the interaction between pleasure and pain. A lot of pleasure and moderate pain, shame, and abused inner struggle make your heart satisfied and confused.
