Cybersex, computer sex, internet sex or net sex is a virtual sex encounter in which two or more persons connecte remotely via a computer network send one another sexually explicit messages describing a sexual experience. It is a form of role-playing in which the participants pretend they are having actual sexual relations. In one iteration, 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. Cybersex may also be accomplished through the use of avatars in a multiuser software environment.
