I have no actual data to back this up, but in my anecdotal experience I’ve found that women of higher intelligence seem to be more predisposed to paraphilia, especially anything to do with submission or giving up control.

I postulate that a large part of this is the desire to be freed from the thought process, even if only for a little while. From their descriptions, brain chatter is a serious problem outside of work, to the point of seriously interfering with intimacy and the enjoyment of life in general. To lose control to someone she trusts, and simply follow his lead, would likely be a relief beyond measure.
