I am not going to answer each of your questions, but I will say this about the general principle of the matter:

There are people who dominate (and do it well, leaving wannabes out of this conversation), and there are dominant people. The former are dominators, the latter are dominants.

If you dominate your partner as a matter of sexual play (or as a technique in living, for that matter), then that's one thing.

If you are a dominant person, then you are always a dominant person, just as much as if you have blue eyes in the bedroom, you have blue eyes on the street.

A dominant does tend to be in control a great deal of the time. Remember, however, that a person truly in control of themselves then is able to, and should, determine HOW to behave in various situations. A dominant does not always need to dominate.
