The word masochism refers to the behavior when an individual
seeks self harm or humiliation voluntarily. Masochism is the direct
opposite of sadism. Sadism is when someone takes pleasure in
inflicting harm upon others. Masochism could be of a sexual nature,
but does not have to be. In psychiatry sexual masochism is usually
what is discussed as a mental disorder. Luckily, prognosis is good
in most cases for those treated for the disorder.
