The reason I have skepticism is that there are two types of people who would want an answer to that question:
1) Those that find themselves prone to fetishism and are genuinely curious as to what may cause such unusual stimuli to be 'their thing'.
2) Those that want to use the findings to try to find ways to 'cure' these 'taboo or religiously sinful' behaviors.
Group 1 and Group 2, also, may have some crossover in some regards.
Clearly there would be some sort of shift in research tone to get to the 'curing' aspect, but first you need to see how big the 'problem' is first... statistics if you will.
