Submission is about the release of control. That you are in control most of the time, and want that release of control where pleasure is concerned isn't an uncommon notion. In fact, I'd say most of the submissives I know are the kind of person who thrives at being the alpha person most of the time, and then to their partner/lover they are submissive. I say most, because as with everything in BDSM, there is no universal rule or truth that fits everyone.

So how to go about finding someone. Do as denuseri suggested and attend a munch.
