Mistress since my sessions are more of the role play variety acting is involved at least for me. Before a session I try to get myself in a mindset that the Mistress has hired me for Her pleasure and I act accordingly. That's how I have engaged in activities in session, in the moment, over the years that I would have shied away from if discussing it with the Mistress before the session. I'm always verbal in session. The practice of emailing an outline helps tremendously. One Mistress, now retired, a dancer, teacher and Vegas showgirl by trade is assertive in real life. But she used to discuss with me outside of session Her "alter ego" in session. I knew exactly what she meant. I guess I have one too. And it is verbal.
