In this paper, we explore our experiences working as team comprised of researchers, teacher, and founder and director of a sex education non-profit organisation, who have formed an intra-activist research and pedagogical assemblage to experiment with relationship and sexuality education (RSE) practices in England’s secondary schools. We draw upon phEmaterialism theory and socially engaged, participatory arts-based research methodologies and pedagogies to explore two examples of arts-based activities that have been developed to de-center humanist, male-dominated, phallocentric, penile-oriented RSE. We also demonstrate how these practices enable educators, researchers, practitioners and students to revalue and rematter feminine genitalia, and resist and refigure unsettling experiences of receiving unsolicited digital dick pics.
