If you were to ask about behavior and lifestyle changes, I would say yes. Its hard to say that about a personality though. I have great intuition when it comes to My clients, subs, and slaves. I usually can tell from their personality if they have the potential to change their behavior, good or bad.

For example, I have some slaves on a workout routine, diets, and some in chastity, and these are all lifestyle changes that are because of BDSM. These changes control behavior and mood, but you've got to have a personality willing to let Me enforce these changes to begin with!
