Formal social control of girls has historically focused on disciplining their sexual behavior, and studies show this is still present. This article analyses how authorities describe and give meaning to young people’s sexual behavior when assessing their need of compulsory care. The results show that in the few cases when boys’ sexual behavior is highlighted, it concerns sexual delinquency. The assessments of girls’ sexual behavior largely regards situations where they are exposed to others’ sexual transgressions, risking to victim-blame girls. This is discussed in relation to gendered understandings of sexual behavior and supposed gaps in legislation.
