But this whole "clean" and "dirty" thing, it doesn't make any sense outside my own body, my own head. It's hard to explain it. It helps that the BDSM community tends to frame pain in terms of techniques and less-subjective adjectives, using words like "sharp" or "sting" or "thud." (A lot of people think of "sharp" and "sting" as the same sensation. I usually separate them a bit more, but I'm not sure how many other people separate them.) The BDSM and polyamory writer Franklin Veaux defines "thud" as "sensation of heavy, dull impact” and defines "sting" as "sensation of quick, sharp pain." These words are most often applied to floggers (implements for hitting people, e.g.: "this is a thuddy flogger"), but sometimes the words are used for other things too. I've found that I generally prefer thuddy-type pain, for example, but it took me a long time to figure that out, because there are so many specific sharp sensations that I love. Okay. Now for emotions. This is the really hard part. A while back I got an anonymous comment on my coming-out story that I absolutely love.

But I don't want you to stop doing it.” I can't remember right now if any other "coming out" story I've ever read included such a visceral description of anger. Of course, I think the last time I read one I hadn't experienced it myself. Maybe I never noticed it before, but noticed i
