This paper describes what some 9th grade students think of their sex education in school, especially when it comes to gender, sexual identity, norms and deviation. I have been using group interviews in two different schools, two groups per school. The result of the students' answers have been analysed on the basis of queer theory focusing on gender and sexual identity. The result of the study shows that the students consider their sexual education to be lacking, especially when it comes to gender, sexual identity, norms and deviation. Another conclusion of the analysis is that a sex education grounded in queer theory would be more inclusive.
