Thanks for this post asp. you totally get it. Just because a sub is stoic doesn't mean he isn't giving feedback. Most subs give tons of feedback without saying a word.

I think some here misunderstood My OP and think I am asking for a running diatribe from the sub. Nothing could be farther from the truth. In fact when a sub won't shut up, I think he is lessening his and My experience. It's sort of like a comedian dealing with a well meaning heckler. It just takes you out of the zone. It's the moans, sighs, tremors, breathing changes, flinches, eye contact, etc. that makes the difference.

That being said, I occasionally get a sub that is so stoic that I really can't get a read. None of the above signs are there. It's like nobody is home. The eyes are blank. Nothing. There is nothing there to feed Me. It's just doubly confusing when they later send an email telling Me what an awesome session it was.
