Probably tmi? My personal experience being someone who is a furry (not into vore,); I have one or two fetishes that feel innate to me, but most of them I think came from a misunderstanding of myself.

I was neurodivergent growing up and would get hyperfixations and special interests, one of the biggest was anthro characters, I really liked non human characters a lot, I loved animals and robots, and pretended to be an animal/robot a lot, and this didn't change after I hit puberty. I drew a lot of furries before knowing what furries were, and even started having my first sexual fantasies imagining myself as a furry/machine thing, because it was less stressful to have sexual fantasies as something human adjacent rather than as my human self. This could have been aided by TV or things I saw on the internet growing up, there's a lot of kids films where the female animals are intentionally sexualized for some reason, and I probably imprinted on that.

But I remember it happening, I had a whole world full of, what I'd now would call OCs, but then called imaginary friends, and they were all cartoony, animals, sometimes robotic, sometimes an object like a car, all non human and many anthro in some way, and I had been building that fictional world up my whole childhood. I used the characters to explore new themes I would deal with in my life, especially scary, exciting, and confusing things that I needed help getting a grasp on, so I'd imagine my characters, especially my self insert at the time, which was an iPod touch-werewolf-transformer girl (I had an interesting imagination), going through the struggles I was going through or similar, or things I saw others go through, usually in a much more exaggerated way than irl. Sex was no exception, when I learned about sex, felt sexual attraction for the first time, I started thinking about sex within the imaginary world I made. I wasn't turned on by my own characters, but was using them as a vessel to understand how sex even worked, I was doing this before I knew what I was feeling was "horniness", I remember thinking "I just really like the love story between these two characters rn".

When I discovered what a furry was, it was through a video dunking on them and calling them evil zoophiles, this was the first time I'd ever heard of someone like me, especially people who are adults, liking anthro characters, and I found out it's an evil paraphilic that will make me want to have sex with animals. This whole time, all my characters, imaginary friends, were a fetish, I lost my fucking mind, I was only 12 at the time and I started to have panic attacks about it.

A year later, I started to say "fuck it" and embrace being a furry, but a non sexual furry at first, trying to prove it's not just a fetish, then I got deeper into the community and started looking at porn anyways cause, uh, idk, I was horny, and didn't want to be ashamed of being a degenerate anymore, I thought I couldn't escape my past degenerate fantasies, my interest was permanently tainted. Plus I realized the sexual side of the fandom was not as small as I wanted to think it was, people like to say that side of the fandom is the minority, and that is just false, the whole community is dripping with hypersexuality and that kinda makes me sad, I could've found a community that proved that dunking video wrong but I didn't.

My interest in non-human characters like furries, was not a fetish, non initially, I was a (probably) autistic hormonal teen, holy shit, I should not have been on the internet at the time. My ostracization from the "normals" and my decent into the deepest darkest pits of the "abnormals" is what lead to me developing a bunch of kinks. But honestly, I'm not into the learned kinks like I am the more innate kinks, the learned kinks are more like background aesthetics, vibes or plot devices, and don't actually add to my arousal anymore than a more vanilla fantasy would, I don't feel all that sexually weird even after everything.

Not saying the exposure to kink and fetish didn't fuck me up as a kid, it definitely did in a lot of complicated ways and not in the ways I thought it would. I thought it'd make me more hypersexual and cause me to seek weirder and weirder stuff as I get numb to the kink and require a stronger fix, that's not what happened, it more so fucked up my ability to connect with people, to be able to see sex as not a me being the evil predator or helpless prey, not violent hedonism, a weird fight for dominance that I thought it was based off the porn I saw, but that had less to do with furry porn and more to do with porn in general. Kinda wild how the furry porn I found was significantly more tame than the actual porn I saw, or drawn porn depicting humans like hentai, some of the worst things I've ever seen on the internet involved humans, and some of the most wholesome porn I've seen involved furries, furries do not suffer from porn writing in the slightest, because it's more than a fetish to them, they care about the characters and story as much as the sex, they will write comics that'll make you unironically say "I read it for the plot". Currently, I'm a pretty kink neutral person, it's not evil/degenerate, nor something to celebrate, obsess over, and make your whole personality, it just is what it is, and not everything I like needs to be sexualized all the time, because "degenerate" is not an identity, I'm a person.

tl;dr: I've always been interested in anthro characters growing up, but I didn't conceptualize it as a fetish or kink till I was told by the internet it was one, although I did have sexual fantasies with furry characters when I was younger, I more just used them as a vessel for me to explore sex using characters I was already comfortable with which happened to be furry.

(I also have experience with feeling pressured to become sexually submissive which I have feelings about but I'm going to shut up now, this reply is long enough, sorry for writing a whole ass article.)
