In this paper, violence and ways of representability becomes problematic. We examine two phenomena associated with sexuality, body and erotism: sadomasochism and pornography. We establish some considerations of violence through mobile frameworks that determine their representability, and then, we draw an analysis of sadomasochism as a phenomenon that has been normalized in our time through knowledge-power speeches, and through pornographic culture industry, which leads us to asume that violence in teh sadomasochistic erotic act is unrepresentable. Finally, we conclude that, in an imminent biopolitical regime becomes necessary to wary of the ways that certain practices are normalized and made visible as violence.
