Remember though, that you have your own boundaries. Boundaries are about ourselves, about staying safe and comfortable in our environment and in our relationships. We have the right (and should) know what our own boundaries are and if we are uncomfortable and feel that a boundary of our is being impacted in some way, it is our own responsibility to maintain that boundary.

It sounds like perhaps what you are needing here, actually, is to communicate YOUR boundaries about your own therapy. Do you know what they are? Maybe that's a way to frame this. "Here are my boundaries of comfort and safety concerning therapy. I need to communicate them to you and perhaps explain why they are important to me. In turn, can you (the therapist) respect my boundaries so that we can maintain a productive and focused therapy environment?" That might be a way to get started. Now, be prepared that if the therapist detects something awry with your boundaries, they'll probably want to discuss that. For instance, sometimes we set boundaries that are too inflexible or too open; we don't necessarily start off knowing how to set healthy boundaries. But that would be important discussion to have.
