The nature vs. nurture thing is something I've been interested in and have been taking an informal poll among readers who correspond with me.

I, too, must disagree with Tourguide.

I had one woman tell me bondage was a learned interest for her, but all others felt they were born with it. At this point, I am of the opinion that an interest in BDSM is innate. It can be learned, but those who don't already have an interest usually don't bother, and are often repelled by the idea.

My data is unscientific and best classified as hearsay, but I've heard the same thing often enough now that I believe it.
