Studies have described the phenomenon of voluntary sexual exposure among youth online but only a few focus on the typical young person who has this experience. The purpose of this study was to investigate Swedish youth with experience of voluntary sexual exposure online, with regard to Internet behavior, social background, and psychosocial health including parent-child relationships. A representative sample of 3503 Swedish youths in their third year of high school completed a survey about Internet behavior, Internet-related sexual harassment, sexuality, health, and sexual abuse. Out of those taking part in the survey, 20.9% (19.2% boys and 22.3% girls) reported experiences of voluntary sexual exposure online. Multivariate analysis showed a significant association between voluntary sexual exposure online and a number of different forms of harassment online. Neither poorer psychosocial health nor problematic relationships with parents remained significant in the final model. The results underlined the fact that voluntary sexual exposure online is associated with vulnerability on the Internet among both boys and girls and that there is a need for parents and professionals to better understand what young people do on the Internet and the risks they may incur.
