"I find that misleading. When I think 'Dom', I feel there should be no submission in his heart as far as bdsm is concerned."

I think this is too simplistic a view. Over the years I've met a number of ladies who are sub to men, but Domme to other ladies. How would you categorize them?

And if a Domme likes to have her breasts whipped, or if a Dom enjoys being bound, and they have their subs perform accordingly, does that make the individual less dominant. They are using their dominant trait to further their own pleasure - isn't that dominance?
