I often say that we are what we do, the set of our experiences and of the choices we make throughout our lives.
A submissive can boast of holding extremely intense sessions, but would not be the first one who lies down to mourn at the sight of my “toys” and my attitude, that is, when it comes to prove his words.
And this is where Dommes must use our common sense. And note that a declared sadistic Mistress is saying so 
But it is like this. However much I like the tears of a slave, which can pleasantly turn me on, I enjoy them if I’m the one who has provoked them and always, absolutely always, controlling the situation. I never do a session with a new submissive trusting what he says because I myself prefer to see how far I can take him, groping not only his body but his emotional state as well.
And exactly the same is true of the other role. There was an episode in which a Lady boasted of how sadistic she was and finally she was paralyzed and her face was white as milk during a session with one of my harsest slaves to which she was invited.
And do not get me wrong, because I have slaves who are not masochists, but they give me their pain if that’s what I want to take from them. Now, I have in mind their pain thresholds and sometimes I enjoy (and I am proud) of their surrender leaving a little aside my instincts to savor sublime moments.
We need not to go through life demonstrating or boasting about anything, just being and fully enjoying what we are.
