Bridging people through rapid real time communication is one of the most important functions a chat website can offer.
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.
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).
There are a number of popular, commercial webcam websites that allow people to openly masturbate on camera while others watch them.
Using similar sites, couples can also perform on camera for the enjoyment of others.
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.
There is disagreement over whether cybersex is a form of infidelity.
While it does not involve physical contact, critics claim that the powerful emotions involved can cause marital stress, especially when cybersex culminates in an Internet romance.
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.
