APA Dictionary of Psychology

n. sexually explicit or erotic interaction conducted via digital or internet-based technologies (e.g., text chat, audio, video, webcams, virtual or immersive environments), typically involving real-time sexual communication, arousal, or activity between participants who are not physically co-present. Cybersex generally implies consensual activity between informed participants, with non-consensual cybersex more accurately categorized as digital sexual exploitation or online sexual harassment. To improve specificity, cybersex is more recently referred to as online sexual activity (OSA) or technology-mediated sexual behavior. Also called internet sex; computer sex. Compare sexting.
