I don’t understand the idea of having a Dominant, be it Sir/Master/Mistress/Daddy and not thinking that it is okay or necessary even to communicate all your thoughts and feelings with them. The fact that they are in charge of all your wants and needs makes it necessary for them to know what they are.
Assuming this agreement has been entered into consensually I would also assume it’s because it’s reciprocal and both parties are getting their needs met. If that is the case then why would one not want to know what’s going on with the other at all times? How can your Dominant possibly be effective and a positive force in your life if they are only working with half the information? Essentially you are only telling them half truths ….
As a slave in particular I find it extremely important to communicate all my thoughts. I recognize that in my mind I will do whatever is asked of me any time, any where, without regard for my own feelings on the matter if that is what Sir wishes. (He doesn’t like me to refer to him as Master, so I do not.) I also recognize that He wouldn’t want to hurt me mentally or emotionally especially if he had no idea what was going on. I could only imagine this would bring on huge amounts of guilt and uncertainty once it was found out. I want to serve Sir, not hurt him.
Sir’s job is to take care of me mind, body and soul along with getting whatever he wants and desires from me. If I withhold part of me from Him then He is only doing half His job, and I am failing as His slave.
