I was wondering if any of you have good advice on how to stay in submissive mode
I don't think I really stay in submissive mode. My life doesn't really let me continually stay there even if I did want to. My Dom usually has a trigger that helps me get there quickly, whether a look, a word, or a command it all helps to bring me back to submission.

being able to talk the way your Master wants
I think for me this would take alot of practice and patience. All Doms are different so this is subjective to the person....each would have a preferance how to speak or display us.
