This article aims to question—from the perspective of posthumanist theories—the normativity of human sexuality, located at the borderline between the technological imminence of AI sexbots and the humanistic legacy of Western socio-cultural constructions, governed by masculine bias. The purpose is to emphasize that as long as this normativity remains encapsulated within the boundaries of the culture of Western metaphysics—characterized by the anthropocentrist, dualist, and speciesist paradigm—the sexual domain will permanently constitute an antagonistic ground of discrimination and binary hierarchical relations, an aspect that will permanently attract the possibility of manifesting sexual solipsism. The general objective follows the paradigm shifts that this hypothesis of sex with weak/strong AI sexbots can bring about on an ethical level, along with the risks/benefits that may appear on the social level. The theoretical objective consists of a posthumanist analysis of the phenomenon of weak/strong AI sexbots, which calls into question both the ontology of the person and Rae Langton’s sexual solipsism theory—specific to the humancentric paradigm. The methodology used is that of the critics/arguments brought from the perspective of posthumanist philosophy (Rosi Braidotti, Francesca Ferrando), supplemented by the deconstructivist philosophy of Gilles Deleuze, in the direction of arguing for a postdualistic rhizomatic sexuality, which upholds an ethic of diversity and of continuous becoming within the limits of an emergent ontology of differences.
