This paper presents findings from focus group interviews conducted in Swedish government group homes for young people with a history of psychosocial problems, substance misuse and criminal behaviour. Participants were asked to reflect on a newly developed sex education curriculum located within a harm-reduction paradigm prior to its implementation. In addition to appreciating the proposed 10 sessions, young people positively evaluated the proposed dialogical and norm critical teaching style as likely to facilitate productive discussion about sexuality. Findings will contribute to future implementation of the sex education curriculum across a range of institutional settings. Results also highlight the democratic aspects of involving vulnerable young people in matters that directly concern them, and underline the importance of properly contextualised forms of sex education.
