I can only speak from own experience. Basically I am absolutely uninterested in putting myself into any sexual situations (with others) or fantasizing about it. I don’t even have the idea to put myself in any fantasies, it doesn’t occur to me.
What I do like is watching others/reading about others, but other than in a fanfiction setting it’s not about those other people since they’re anonymous/interchangeable for me. what I like is watching bodies, listening to the noises etc.
on a similar note, though; I know it feels good to finally be able to put a label to feelings that one felt isolated with, but one should always keep in mind that you don’t need any labels to make whatever you feel valid. I can guarantee that you are not alone with whatever you are feeling, there will be thousands of other people that have the same desires/thoughts/whatever. There is no need to see everything in a negative light, and/or to make yourself feel bad.
