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.
In "real cybering" personas often remain in character throughout the entire life of the contact, to include evolving into phone sex, and meatspace encounters while in character, as a form of improvisation, or, nearly, a performance art.
Often these personas develop complex past histories for their characters to make the fantasy/roleplay even more life like, thus the evolution of the term "real cybering".
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.
