This study was conducted among a group of Swedish teachers and a class of 14-15-year-old students and explored pornography education as part of secondary school sexuality education. Data were generated using mixed methods including teacher-researcher meetings, participant observation in class, student interviews, and teacher evaluation meetings, and were documented in the form of audio-recordings and notes. Donna Haraway's work on string figuring was used to trace the threads constituting pornography education. A four-threaded string figure materialised how Swedish schools' gender equality stance could provide a sound foundation for engaging with pornographic material. However, a gender-neutral approach to teaching frustrated these aims. The figure also foregrounded how normative societal debate makes it troublesome to acknowledge other than negative perspectives in teaching, problematised the engagement of students and a focus on pornography. Finally, the figure showed a discrepancy between the curriculum's overall aim and the goals of subject-specific syllabi, making it troublesome to link the topic of pornography to specific school subjects. In summary, pornography education came into being as a complex figure in relation to adolescent sexuality and the school's mission to provide a form of sexuality education that both problematises gendered sexual scripts and dominant norms with regards to pornography.
