Desires may be viewed as emotions that are structuring and structured by social inequalities. This paper examines how sexual desires may surface in everyday classroom interactions. It argues in particular that anti-racist sex education requires not only an awareness of a racialisation of sexuality but also of the sexualisation of race. Focusing on students' images of desire and a selection of music video stills, the paper investigates in which ways racialised and gendered desires are relevant to students' imagination -- and how they negotiate them in the classroom. Young people's ethnosexual imaginary reveals an affective investment on the part of adolescents in racialised sexualities in visual culture. In the context of participatory arts-based workshops, the paper analyses how images of racialised desires are transformed into material objects of boundary work. The paper concludes by proposing the re-enactment of young people's imagery as a means to open up an affective space for negotiating desires and disdain.
