This paper theorises the ways in which non-binary gender is rendered invisible through binary Yes/No sexual consent education. Judith Butler's framework of gender intelligibility is drawn upon to consider the absenting of non-binary youth from consent education. We suggest that the undoing of the hegemonic colonial gender binary also be a project of consent education. Consent education is often taught through a highly gendered lens underscored by the 'miscommunication hypothesis,' which posits normative binary gender roles as the underlying cause of sexual violence and fails to account for how non-binary youth experience and navigate consent. Furthermore, we examine how binary Yes/No consent education negates non-binary gender by rejecting the grey area of consent. The dismissal of grey area experiences is problematic for non-binary youth as ambiguity around consent may be more prevalent amongst non-binary people due to increased experiences of trauma and the common experience of gender dysphoria. Despite this invisiblisation, non-binary people have formulated their own modes for navigating sexual pleasure and consent. We call for more research into how non-binary youth are invisibilised by binary consent education as well as how these youth are challenging normative consent and reimagining sexual cultures that centre interdependence, mutual pleasure, and care.
