I hate slave-speak! It's so unwieldy when trying to make a sentence not using pronouns. I can't stand trying to read it in chat rooms and such. That's just me, though.

Okay, now that my personal opinion is out of the way, we can try to figure out why he wants this. Are you a slave or submissive? It's my understanding that Master/slave relationships are a bit more strict than Dominant/submissive relationships. Not allowing you to refer to yourself in the first person is a way of reinforcing the idea that you are his possession and, therefore, not your own person. This type of training is designed to keep that thought always at the foremost of your mind. If you feel strongly about it, approach him in a respectful manner and try to discuss your feelings openly and honestly.
