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.
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.
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".
Alternatively, it can be considered a form of sexual roleplay that allows the participants to experience unusual sexual sensations and carry out sexual experiments they cannot try in reality.
Amongst "serious" roleplayers, cybering may occur as part of a larger plot–the characters involved may be lovers or spouses.
