This text presents how Freud thinks about the masochism. In 1915, it is the return of active sadism in a passive drive which is characteristic of masochism, always secondary. In 1919, he sees in masochism the genesis of perversions. And the article of 1924 knows a primary masochism and distinguishes erotogenic masochism, feminine masochism and moral masochism. After Freud, many studies of clinical forms of masochism can be noted, and in France there is a thesis about the masochism as a first psychic link (Benno Rosenberg, Marilia Aisenstein).
