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.
Often these personas develop complex past histories for their characters to make the fantasy/roleplay even more life like, thus the evolution of the term "real cybering".
Cybersex provides various advantages: For many the primary point of cybersex is the plausible simulation of sexual activity, and this knowledge of the other is not always desired, but this is also criticized as the emptying out of embodied relations.
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.
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.
