actual serious list of the fetishes i could see flowery having but everyone is too cowardly to consider. i am releasing this into the world like a biblical plague.
I think Chairery could be used as soft evidence that he'd be fine with being object tfed.
As previously established i think him having a quicksand/burying fetish feels fitting AND is unfortunately an extremely fucking funny thing for a plant to have.
I think flowery doesn't necessarily Have a feeding/stuffing kink but like. he could. he could… it's borderline. i think he likes giving people food in both platonic and romantic contexts but like… he does kind of like watching people he likes eat a bit more than the average person.
I don't think he's into macro/micro as a sex thing puts finger up BUT! with his weird hangups about being unable to return kindness as a flower he'd get deeply strange about someone getting smalled shrink ray style. If you get small as a surprise/inadvertent thing I think it would be kind of distressing to him if he couldn't fix it with funny status effect clearing pollen, but if it was a planned thing it's going to result in some weird ennui in the 'taking care of something small' tack.
I think if he was truly into macro/micro or growth he would have made himself very big or very small to begin with (we know from the break convos at the cafe that the flowers Decided to be humans, and there's multiple instances of dialogue indicating they flat-out Are Shapeshifters, a la funny netskie. flowery looks like that because he wanted to look like that. he could have chosen to be shorter.)
Despite this blog's entire thing, I actually don't think Flowery would be into vore (or at least not hard vore/what a humanoid person would view as vore) but I think if the person he was into was into it he'd spend a frankly distressing amount of time figuring out a way to Safely(tm) have it or something resembling it happen.
I don't think he has stomach acid </3 and anything he eventually comes up with is going to just end up being kind of a lady's slipper/coryanthes situation, because those are tried and tested plant 'trap a thing inside you and get pollinated and the pollinator does not die' templates.
(as aside: NOT PITCHER PLANT OR FLYTRAP. those are the ones that kill bugs. no good for fun light stuff, which on the whole i would say is what flowery 'won't even kill you if you lose the boss fight' chapter 5 would tend towards generally.)
Even in the world of 'digestion with reformation' i think he flat out Would Not Like That/be worried like, the actual literal entire time. (at least as a pred. if the shoe was on the other foot… hm. i do think he might get the appeal then.). he's an endophagy guy in a hard+fatal world… I think Flowery does have a thing for teeth/biting and being licked, though (lot of pollination requires physical biting/buzzing for pollen to release proper from anthers.)
on the topic of 'not into what a humanoid would view as vore generally' Anything that involves him using roots instead of vines is basically just mawplay/prevore teasing for plants. if he has a thing for the actual plant vore/absorption involving roots, The Ruins (2008) style, it's something he is never directly mentioning because that would kill people for realsies, and likely hurt the entire time at that.
-(Despite this, i do think he'd have Opinions on monster funeral stuff considering how we know dustners work and the well. Interesting Way that likely interacts with 'putting dust on a flower that then enters a dark world'. since that's like, The Inverse Of Fatal vore i think he'd be more amenable to that. vore/absorption that revives the dead…
tldr : pointing at the wedding bouquet flower you know that thing would eat you if you died right? )
A whole ton of stuff of the 'would be extremely willing to do but would be reluctant to bring up' genre. The idea of constricting someone or being tied up is cute to him because he likes being squeezed/squeezing people, but i think he's aware that it could be scary. consentacles guy. guy who has no context of what safe bdsm practices outside of maybe whatever porn asgore watches are but is slowly recreating them from first principles.
Imagine the 'what do you think of gay marriage' 'to me all marriage is gay marriage' but it's about clothed sex. he's already clothed (in the shape of a self-described handsome guy). he's already shapeshifted. the human body is fake. it's dolls, my evil opinion is the ever-classic 'petalmantle' and 'sundaybest' are literally his own petals+leaves as a funny shell for a mass of vines and roots bundled up into something cute and relatable.
Honestly, with all the flowers being in his insides post being cleft in twin I honestly would Personally argue for null genital on his human body or it very emphatically NOT being just a pistil/stamens being used as an analogue for cock or whole flower as vagina... his entire thing is 'wanting to know what it's like to be human+what being a monster is like', so i think his genitals situation should be at MOST an abstract conceptual half-remembered thing or flat out nullge. simply does nooot have the details figured out, he only has so much visual reference. actual full-on 'smooth nothing' is also solid.
May have a thing for seeing people he likes splattered in staining fluids/mess and the cleaning of said mess. fetish for the mobile game cleaning off mud minigame. something something 'i think i hauve covid' over seeing a monster covered in burrs, especially so. seed dispersal freak.
I think Flowery likes armpits and sweat/scent but I can't prove it.
I also think he'd be into watersports but it's one of those things where while it's a pretty innocuous fetish to a lightner it would actually be a 'oh a little risky' thing for a flower... the nitrogen and salt content in urine is a bit too nutritious and can fuck with stuff.
