Masochism

Masochism refers to emotional, psychological and/or sexual pleasure that is gained through physical pain or humiliation. This term was added to psychiatry in the late 19th century by Austrian psychiatrist Freiherr von Krafft-Ebbing and is included, along with sadism, in the DSM as a Paraphilia. It is the opposite of the term Sadism (taking pleasure in causing pain) although these two paraphilias are often jointly referred to as Sadomasochism.
