pain slut? cane slut?

Several months ago, my former Dom told me that I was a pain slut in the making. I told him I was pretty sure that he was not correct. A couple of weeks ago, my Sir asked Ma'am if she thought it was possible that I'm a pain slut and don't realize it. Ma'am told Sir that she really didn't think so. A few days ago, with a certain look in her eye, Ma'am asked me if I thought it was possible. And after I reported the weekend's events to Sir....he asked Ma'am if she was sure I'm not.

I'm starting to wonder what exactly I'm putting out there that has these three thinking I'm a pain slut...

Perhaps my definition is faulty? In the simplest terms, I consider a pain slut to be someone who enjoys and/or is aroused by heavy pain. I don't think that person has to be a submissive and I don't think that the dynamics of power exchange play into it. Is this different from the common perception?

For my part, I don't enjoy pain for pain's sake and I seem only to deal with it well when it is within the framework of power exchange. In this setting, I find that I can take quite a bit of pain as long as I know that it is my Doms' pleasure. The heavier or more long term the pain, the more reassurance and reminders I need of their dominance and their pleasure to get through it. My pleasure and satisfaction come from enduring the pain as well as I can and from knowing that doing so has pleased them. Any arousal I experience comes from the power exchange aspects in play at the time and not from the pain itself.

But...this past weekend I received a caning so severe that it pushed me right up to the edge of my capacity to take it. Afterward Ma'am and I discovered that I was very wet which seems to be contrary to my belief that I'm not a pain slut. I hadn't consciously felt aroused before, during or after my caning but the undeniable evidence was there between my legs...

Am I really a closet pain slut? Or maybe a cane slut? Or....???
