There is disagreement over whether cybersex is a form of infidelity.
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.
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.
There are a number of popular, commercial webcam websites that allow people to openly masturbate on camera while others watch them.
