Cybersex, also called computer sex, Internet sex, netsex and, colloquially, cyber or 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.
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.
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.
the increased popularity of webcams has raised the number of online partners using two-way video connections to "expose" themselves to each other online—giving the act of cybersex a more visual aspect.
Cybersex is commonly performed in Internet chat rooms (such as IRC, talkers or web chats) and on instant messaging systems.
