In some contexts cybersex is enhanced by the use of a webcam to transmit real-time video of the partners.
Channels used to initiate cybersex are not necessarily exclusively devoted to that subject, and participants in any Internet chat may suddenly receive a message with any possible variation of the text "Wanna cyber? " or a request for "C2C"/"C4C" ("cam to cam" and "cam for cam", respectively).
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.
