Drawing from a practice-based research study in Swedish secondary schools, the aim of this paper is to explore how facts and values are made and unmade as separate and entangled phenomena in sexuality education. In this exploration, we work with a posthumanist approach - agential realism - and more specifically the concept of agential cuts. The empirical material draws from two moments in the teaching of sexuality education, one concerning nakedness and one concerning gender diversity. The analysis puts forward how the lesson topics in relation to school subjects and exercises become significant actors in how facts and values are enacted in the teaching. This implies that facts and values are enacted together-apart within a relational set of interdependency and hence are always present although temporarily more forcefully and ephemeral. To conclude, we discuss the complexities of how facts and values are part of enacting the everchanging knowledge area of sexuality education and urge for acknowledgement of this matter.
