I think you are right, at least in my case. I work in a financial firm where I'm an executive secretary. I'm extremely kept extremely busy, and, in essence, really run the office. For me, being helpless is sort of an escape, I guess. But then, I'm not really the true "submissive" in that I like to be "forced" to submit, not do so "willingly".

I hope that helps with your research.
