I used to believe that I was a masochist. Now, I think that He has beaten it out of me lol.
I have noticed something interesting though, I can, to a certain extent, get off on pain. But, getting off on pain itself is not quite the same as getting off on Alpha enjoying my pain. At first, I think it was difficult for Him to reconcile causing me pain and liking it, with the love He has for me and His desire to see me free from suffering (though, interestingly enough, these days He only has a problem with my suffering if it is caused by someone or something else. That's sweet...I think...). And then? I liked it and I wanted more. Until He discovered He liked giving it and there was never any need to wish for more. Ahem.
I have observed several things about physical pain--add words to it and it becomes much more bearable, more like a high than anything else, and He only gets off on my enjoyment of it, which in turns increases the pleasure I get from pain. Of course, while He doesn't get off on punishing me, He does take an incredibly perverse enjoyment from putting me back in my place. Sadistic bastard.
Anyways, the concept I have floating around in my head is really about His sadism feeding my masochism and vice versa.
I can be right on the edge, where it's really to much, I'm not able to get off on it anymore and I just want an end. Then, something will indicate to me that He's getting off on my suffering (fucked up sounding shit maybe lol, but anyhow...), and it makes me fly. Something about His enjoyment of it changes everything. It makes pain malleable and fluid, something that is as much pleasure as suffering. It leads to a vulnerability and surrender that goes beyond physical sensation to a mental level that is somewhat difficult to describe.
While control figures much more into our dynamic than sadomasochism does, it's still a fairly integral part of our play. To the extent that it's always there in some aspect or another.
When I think I'm done, He feeds my masochism with His enjoyment of my pain. My masochism feeds His sadistic tendencies and it becomes one of those rare full circle events.
Which is nice because it's not the same experience if He's not truly enjoying it, and apparently, the pleasure/pain continuum leads to some very attractive reactions and sounds on my part lol.
