The problem with Jiggy's first post is that it seem's to assume that being into BDSM is something wrong. Perverted sexuality if you will.

Here's a theory. Maybe submitting or dominating are at the very core of what human sexuality is all about. Our culture and huge brains allow us to cover this up. People are often so uptight about their sexuality that they don't even admit to themselves what they like.

Emotional crises, no matter what shape it may take can help us question ourselves. Question the very core of our being. Shock us out of a sleep, and help us shed the bullshit and false goals in life. At least it explains why so many in the scene has had various traumas.

Once a person has entered the rabbit hole there's no going back. I've never heard of people who stop being into BDSM. They might stop being part of the scene, but the fantasies never stop.
