It's a good question, I find the mechanics of fetishes quite interesting.
I think that in my experience, some fetishes are products of internalized emotions and experiences and maybe sometimes a symptom of a brain being rewired from obsessive porn consumption. These kind of fetishes should probably be looked at if they are causing you issues.
Where as other Fetishes are harmless things that you find extra stimulating, regardless of their reasoning.
All anecdotal of course, but for example in my case after I went through several beatings and sexually assault as a teen I felt very emasculated and over the years my porn use and fetishes became a way for me to turn this deep buried suffering into an sexualised outlet.
The key I think - is that a part of me knew I was doing this and so it was not a harmless fantasy or fetish that I got off on, it was a temporarily pleasurable but ultimately demoralizing experience that I kept going back to in order to avoid things that meditation would later bring me to converse with.
The reality was that these fetishes were an accumulation of my previous pain and the subsequent porn use.
Point is, that whilst not everyone's had the experiences I had growing up - I've seen *a lot( of people in the likes of nofap over the years who are experiencing similar things. The way to know is to stop any porn or external stimuli and after a while your desires and fetishes revert back to a more natural primal state of attraction to women, which I think contributes to peoples extrapolations of super powers.
And I think at that level the fetishes you have shouldn't be too much of an issue. Providing you are not reliant on them for the main source of sexual gratification then you can just have fun with them and not worry too much about what others think about it - as long as you are properly happy and enjoying yourself.
Some acts like eating pussy or loving feet may seem submissive but that's really more of a conditioned perception based on your own perspective than an reality, and so long as you're both having fun there's little harm to be done.
