Online sexual engagement was also found to be associated with lower levels of psychosocial well-being, in particular less mental health. However, the direction of these relationships often remained unclear since longitudinal studies are scarce. Further, most existing studies were based on non-representative adolescent samples. The current study examined the prevalence of sexting, sexy self-presentation and online sexual victimization among a representative sample of German Internet users aged 14 to 64 years. Longitudinal relationships between online sexual engagement, victimization experiences and psychosocial well-being were investigated over a period of 1 year. Our results indicate that online sexual engagement and victimization experiences are relatively widespread, and, to a certain degree, also occur among older individuals. Confirming previous findings, our cross-sectional results show that online sexual engagement, victimization experiences and mental problems are intercorrelated. Concerning long-term associations, we detected a significant relationship between sexting willingness at T1 and more victimization experienced one year later, while no significant longitudinal associations with lower levels of psychosocial well-being were identified.
