Well here's My two cents worth. I feel that this Dom has unreasonable expectations. If, during your testing period, he has so much control that he is not allowing you to release your bladder when needed....I feel this very irresponsible. And potentially harmful to you. The after effects of this type of control could cause so many things to go wrong. I personally think it's just plain stupid. And if I were you, I would start throwing up the red flags. This is how slaves are trained. But usually not until there is a great deal of communication between D/s. And even then, I would be leery. Use your instinct, as most times it will be correct. But My personal opinion is that this Dom has ego issues. And I would run, and run fast....If he is treating you like this during your initial testing period, I feel that it will continue after the trials are over. And as far as getting better....I highly doubt that would happen.

Trust your instincts hon...they're usually right.
