Cybersex, also called computer sex, Internet sex, netsex and, colloquially, cyber or cybering, is a virtual sex encounter in which two or more people connected remotely via computer network send each other sexually explicit messages describing a sexual experience.
In online worlds like Second Life and via webcam-focused chat services, however, Internet sex workers engage in cybersex in exchange for both virtual and real-life currency.
Cybersex can be utilised to write co-written original fiction and fanfiction by role-playing in third person, in forums or communities usually known by the name of 'A Shared Dream'.
Cybersex is commonly performed in Internet chat rooms (such as IRC, talkers or web chats) and on instant messaging systems.
It can also be performed using webcams, voice chat systems like Skype, or online games and/or virtual worlds like Second Life.
In several known cases, Internet adultery became the grounds for which a couple divorced.
