Talk for the most part is distracting. Good massage requires concentration on the part of the therapist. However, feel free to give feedback if any manipulation is uncomfortable or if you would like something done longer or differently. It's you who've come to this encounter to feel good. Let the therapist know if you are very ticklish.
Strokes can be varied.
Normally this is not a problem unless you are very ticklish. Just lie there. Allow the therapist to move your limbs into whatever position is required. Be a rag doll. Don't try to be helpful.
