Hiya. I'm far from being dominant, but here's my take on the subject:

I think, like Psynymph, that a natural dominant is one who has the innate tendency to dominate in them. However, I personally disagree that a natural dominant necessarily has to be a leader in work, etc, or other forms of daily life. In fact, I might go so far as to say that a large number of innate dominants and submissives project entirely opposite images of themselves at work/school. IMHO, the only thing that separates the natural dominant from the learnt, is that the natural dominant, instinctively yearns to dominate his submissive, and instinctively knows how. I agree that the people who never had dominant tendencies before meeting their partner but still meet the two conditions listed above would be a very grey area, but I'd classify them under natural, still. I would consider the (learnt? unnatural?) dominant as someone who doms to try and satisfy his partner's yearnings, instead of from some need within him.
