i can get furious with my dom - usually when i feel like He is ignoring me or not giving me the attention i want.

i recognise it as childish - He really never does anything to truly deserve my anger.

As to expressing it - sometimes. Usually i come to my senses and get over it before i feel the need to say something.

If i am silly enough i express it when i am still really angry and in and accusing way, full of You did/ didn't do this and i want that. And that's never a good idea, because He deals with me like the child i am acting like - says He won't continue conversation unless i speak reasonably and with respect, then punishes me, NOT for feeling the anger but for the disrespectful way i express it.

If i express it in a more sensible and respectful way, not in the heat of the moment but calmly tell Him i am upset about something and tell Him the reasons, He will talk to me and explain His position and sometimes reasons and talk me through my reactions and over reactions.

He's yet to apologise to me - but He's also yet to do anything that really warrants an apology.

i think it's probably impossible to have a close relationship with anyone without getting angry with them sometimes. And some Doms especially know just what buttons to push with their subs cause they know them so well. But i personally don't recommend confronting your Dom in anger.

Hope this helps
