It is totally up to you. Whether or not you are sadistic in your dealings with you sub is up to you. No one can tell you how to run your relationship except you and your sub. So, if you are not comfortable in a cruel role don't do it.

My Lady is not into that kind of behavior either and she won't do it. Personally, I am not into humiliation as that is a hard limit for me. We don't do that. We are responsible for our relationship.

It all comes down to this, you learn what is out there, what excites you, what you are and are not interested in, and shape your relationship accordingly.

After all, you are the Dominant. No one, not even another Dominant can tell you how your relationship should work or what it should look like.
