Sex in a computer simulated virtual reality, esp. computer-mediated
sexual interaction between the VR presences of two
humans. This practice is not yet possible except in the rather limited
form of erotic conversation on MUDs and the like.

ha ha only serious projection of things to come.
When we can sustain a multi-sensory surround good enough for
teledildonics, then we'll know we're getting
somewhere.
