Do you know or are you a dominatrix?

I know a girl who is a dominatrix..she keeps her clients on the QT very hush, hush...but she does tell me some things. Like s, whips, cleaning, role play, belittling? Some of her clients are business men, I think ones a cop? Do you know any one who is a dominatrix? would you be one? and for the guys would you like to be dominated...? and have you ever been to a dominatrix?
