I would also have to say Yes. What else would a person have to go on, other than fantasy? Without body language, facial expression,etc. one would most likely fill in the gaps with their own fantasy. As far as filling a void in RL, perhaps for a short time. I can't imagine that it would be gratifying for very long, if anything it may create dissatisfaction, a longing for those voids to be filled in RL, which in turn could be a good thing don't ya think?
