All the more reason to attempt it. Just do your best. Try talking without thinking about it. The reason being if you talk out loud without thinking too much about it you build a better connection to your internal states.

My dialogue sometimes goes something like this. I've got an itchy nose, I feel silly talking about it. My big toe is throbbing, my hands feel cold, my mind just went blank I wouldn't have a clue what to say anymore I wish Paul would get on with it, is this over soon it's bugging me. Paul starts talking again. Ahh what a relief I can shut up now.

Other times it just flows. So give it your best shot um and ahh if you must or try focusing on just one part of the body a hand for example might attract your attention go into detail describing that it gets easier once you've done it a few times and the benefits are a better body mind connection.
