I see the discussion sort of went off the tracks but I am going to put in my two cents.
Though there are so many "categories" out there, Dom, sub, little, pet, Master, slave, it is just insane to try and stick yourself into just one role.
The Dom I know and love, is articulate, strong minded, and can have quite the intense presence when in a room. BUT along with that he is also kind, gentle, fun loving, and loves to make people laugh. So many out there think a Dom is someone who is always "Dom" all the time. Always on the ball and ready to give orders or direct a sub but in my opinion, it isn't like a light switch. Whatever your "role" may be, Dom or Master, sub or slave, it just comes naturally. You don't have to force your body or your mind to have that release. Those that even identify as a switch and enjoy both roles have it come naturally to them dependent on the person they are with (or so I have been told anyway).
In my opinion, a "true Dom" is anyone who can respect not only subs but fellow Doms, they don't have to push out their chest to prove their status. They are genuine in their care of a sub and know how to play the game by the rules, no cutting around the corners bullshit.
