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".
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'.
In situations like this, the people typing often consider themselves separate entities from the "people" engaging in the sexual acts, much as the author of a novel often does not completely identify with his or her characters.
