Cybersex can occur either within the context of existing or intimate relationships, e.g.
Cybersex, also called computer sex, Internet sex, netsex and, colloquially, 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.
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.
The quality of a cybersex encounter typically depends upon the participants' abilities to evoke a vivid, visceral mental picture in the minds of their partners.
Imagination and suspension of disbelief are also critically important.
Cybersex is commonly performed in Internet chat rooms (such as IRC, talkers or web chats) and on instant messaging systems.
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.
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.
Some online social games like Red Light Center are dedicated to cybersex and other adult behaviors. Cybersex may also be accomplished through the use of avatars in a multiuser software environment. In Tiny MUD variants, particularly MUCKs, the term Tiny Sex (TS) is very common.
