-Do you feel the urge to dom and sub a single person at the same time? Maybe at different times during the same scene?

It actually doesn't depend on the person themselves, but really it depends on both the mood I'm in and how well they respond to it.

-Do you dom and sub at the same time, but with different partners (I'm a sub for this person, but a dom for this person)?

Nope, I'm a one-woman show right now.

-Do you take turns with your partner (tonight, I'll be the boss, tomorrow night, you be the boss)?

We take turns, but it's never planned.

-Do you feel like a dom/sub for long periods of time, then feel the need to switch again (i.e. feeling like being the sub for weeks/months/years then kind of feeling dom-my for awhile)?

Nope, I honestly enjoy both equally almost all the time : )
