I really have never felt much of a power imbalance in therapy. My sessions were very much a dialogue - very give and take. I was free and felt free to express my opinion as to whether what we were doing, what the therapist was saying/interpreting, etc. was working or accurate and knew they would listen and we would come to a resolution on those issues together. We never really had to have discussions about boundaries or rules or touch, etc. because they just kind of naturally fell into place as we worked together - never really a power issue there.
