This work exists in exchange between the object and the beholder. In this case, the relation is exacerbated by the erotic action. It's something like a protocol that plays with the expectations of a viewer, conditioned by contemporary art. Sex is a kind of tool to analyse a situation. In this case it's the perception of conceptual art. When I show myself masturbating in front of a work of art, I don't want to express my sexual independence. An error is introduced: the sight of panties damages for a few seconds the intellectual assessments.
