Amongst "serious" roleplayers, cybering may occur as part of a larger plot–the characters involved may be lovers or spouses.
It can also be performed using webcams, voice chat systems like Skype, or online games and/or virtual worlds like Second Life.
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.
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.
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.
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'.
