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.
Without continuing to draw off our historically ambivalent faith in embodied relations, techno-sex quickly becomes hollow, unsatisfying, no more erotic than collecting answers to what-are-your-measurements questions. By continuing to draw off that ambivalent faith, techno-sex and the many other practices of disembodying interaction contribute to a changing and increasingly abstracted dominant ontology of embodiment.
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.
In one form, this fantasy sex is accomplished by the participants describing their actions and responding to their chat partners in a mostly written form designed to stimulate their own sexual feelings and fantasies.
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.
Cybersex can occur either within the context of existing or intimate relationships, e.g.
among lovers who are geographically separated, or among individuals who have no prior knowledge of one another and meet in virtual spaces or cyberspaces and may even remain anonymous to one another.
