>>41694709I should also add that you can extrapolate the power play aspect to explain the majority of really out there fetishes. If it's not the main reason, it's at least the backbone that makes it work. The rest is usually explained by it being some sort of abstract feeling that you can't experience (or can't experience as strongly) in the real world (eg. inflation, the increased pleasure that comes from hyper, etc.). The exception is feet/paws as that's just a brain wiring thing, but even that can be strengthened by this.
Possession revolves around loss of control to another party- both physical (your actual body) and decision making wise (what you do)
Inflation goes back to that "anything but human is a downgrade" aspect plus the previously mentioned alien feeling of inflation which you can easily imagine as being pleasurable (I imagine it as the feeling of being really fat, but without the unpleasant grogginess or droopiness of your flab)
Micro/macro is the same general motivations behind TF
If you're still not satisfied, name a fetish you don't understand and I'll explain it to you
