Consent has become a key concept in sexual relationships. At first glance, it seems clear. But is it really like that? This text reflects on the nuances, fissures and paradoxes that accompany it. Can the desire be verbalized with absolute clarity, without any ambiguity? The author explores the path traveled between "no means no" and "only yes means yes" from philosophical, historical and political perspectives and, contrary to the dominant discourse, defends not leaving aside the first for the benefit of the second.
