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 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.
Imagination and suspension of disbelief are also critically important.
There are a number of popular, commercial webcam websites that allow people to openly masturbate on camera while others watch them.
