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.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.

It can also be used to gain experience for solo writers who want to write more realistic sex scenes, by exchanging ideas like sex position.

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.

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.

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 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.

Cybersex can be utilised to write co-written original fiction and fanfiction by role-playing in third person, in forums or communities usually known by the name of 'A Shared Dream'.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).Cybersex can occur either within the context of existing or intimate relationships, e.g.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.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.
