Based on its prevalence, there is an urgent need to better understand the mechanisms, opportunities and risks of sexual interaction in digital contexts that are related with sexual arousal. While there is a growing body of literature on SIDC, there is also a lack of conceptual clarity and classification. Therefore, based on a conceptual analysis, we propose to distinguish between sexual interaction through, via, and with digital technologies. Sexual interactions through digital technologies are face-to-face sexual interactions that have been started (...) digitally or are accompanied by digital technology. Sexual interactions via digital technology are technology-mediated interpersonal sexual interactions. Sexual interactions with digital technology occur when the technology itself has the role of an interaction partner. The three types of SIDC and their respective subtypes are explained and backed up with empirical studies that are grouped according to two major mediators: consent and commerce. Regarding the causes and consequences of the three types of SIDC we suggest a classification that entails biological, psychological, social, economic, and technological factors. Regarding implications of SIDC we suggest to focus on both opportunities and risks for sexual health. The proposed conceptual framework of SIDC is meant to inform future research. (shrink)
