Resum

During the last decade, the number of people using the Internet for sexual purposes has increased exponentially. However, most studies conducted so far have analysed Online Sexual Activity (OSA) of adolescents and young people, meaning that we have few information on how this phenomenon is expressed across the lifespan. The aim of this study was to analyse three aspects of OSA (prevalence of different OSAs, motives to engage in OSA, and excessive and problematic engagement in OSA) in a large sample of individuals in different developmental stages. A self-selected sample of 8040 individuals between 12 and 85 years old were recruited and completed an online survey. Participants were distributed into five age groups and compared (<18 years old, between 18 and 25, between 26 and 40, between 41 and 60, and >60). OSA was highly prevalent across all the developmental stages, including people older than 60 years old. Differences according to the age in the use of the Internet for sexual purposes were small-to-moderate, but we identified some age-related trends in different aspects of OSA. Finally, gender was important when it came to understanding these minor age differences. This study provides a preliminary foundation for identifying the unique characteristics of OSA across the lifespan.
