In the "one off" session, I would agree with you. It's a transactional, negotiated scene. But if you are fortunate enough to develop a deeper bond with a pro Domme it can be so much more. She can push limits safely beyond where you ever thought you would go. It can be a journey, if you seek it and let it happen. Choosing to take that journey takes strength. I think that is what others are trying to convey here.
