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).
Cybersex is commonly performed in Internet chat rooms (such as IRC, talkers or web chats) and on instant messaging systems.
It is also fairly frequent in online role-playing games, such as MUDs and MMORPGs, though approval of this activity varies greatly from game to game.
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 some contexts cybersex is enhanced by the use of a webcam to transmit real-time video of the partners.
Due to this difference, such roleplayers typically prefer the term "erotic roleplay" rather than cybersex to describe it.
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.
It can also be performed using webcams, voice chat systems like Skype, or online games and/or virtual worlds like Second Life.
The exact definition of cybersex—specifically, whether real-life masturbation must be taking place for the online sex act to count as cybersex—is up for debate.
Using similar sites, couples can also perform on camera for the enjoyment of others.
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.
One approach to cybering is a simulation of "real" sex, when participants try to make the experience as close to real life as possible, with participants taking turns writing descriptive, sexually explicit passages.
