Ahaa, the truth comes out. You did fine getting your point across, don't worry about that.
Believe me, restrictions and play are MUCH more fun if you've asked nicely for them first. By asking Him what you want and leaving it up to Him to decide, it also means that you're not trying to manipulate Him into doing what you want, another big no-no for subbies. You may have to accept that He will inevitably say 'no' Himself in some cases to whatever you ask for, but that is part of being submissive to somebody else- the decision is His.
Really, you're looking for 'please may i...' or 'please would You...' instead of 'no'. Begging is fun territory to go into. =]
