In my thesis I am going to put under microscope the mechanism of sadomasochistic relationships; the stages of it; how the two parties are related to each other; how they fulfill their roles; what the consequences are of this kind of “perversion” and why they are doomed to failure. I am going to invoke some theorists in order to clarify the subject of sadomasochism. Also, I am going to invoke two novels and two films in order to analyse and interpret the dynamic of sadomasochism.
