Cybersex can occur either within the context of existing or intimate relationships, e.g.among lovers who are geographically separated, or among individuals who have no prior knowledge of one another and meet in virtual spaces or cyberspaces and may even remain anonymous to one another.
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.
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 one form, this fantasy sex is accomplished by the participants describing their actions and responding to their chat partners in a mostly written form designed to stimulate their own sexual feelings and fantasies.
Due to this difference, such roleplayers typically prefer the term "erotic roleplay" rather than cybersex to describe it.
