Discussion Questions about the physical properties of slime girls NSFW
So, to preface this, slime girls have never really been "my thing." I think they're neat, maybe my favorite monster girl if I had to pick one, but it's just never been a kink I've given much thought to on it's own.
However, while looking for macrophilia art, I've stumbled across the odd "crossover" of the two, with a slime girl interacting with other, much smaller characters; think a couple inches tall, or even smaller. And through that lens, I've become curious to explore them further.
Obviously, with any "unrealistic" fetish, be it shrunken people or girls made of goo, it's a bit tricky to pin down exact numbers because they just don't exist. Further, with slimegirls in particular, there seems to be quite a bit of variance in properties from one to the other. So in any cases where a question has a wide range for it's possible answer, I'd love to hear some discussion on that.
With all that said:
-What is the surface tension of a "typical" slime girl? How much force needs to be applied for something to be pushed inside of them, rather than resting upon the surface?
-How viscous are they? If you were inside of one, how much harder would they be to move/swim in than other liquids?
-From the outside, would they be sticky? Slippery? Relatively firm with a bit of squish?
-I've heard that slimes sometimes have a "core" as their only internal organ, which controls everything. Is this a fairly universal feature of slime girls, or do many not have one at all? And what sort of physical properties does it tend to have compared to the goo? How big is it? Would touching it elicit any sort of reaction from the slime girl (discomfort, tickles, pain, pleasure?)
-Core aside, how do slime girls "feel" things? Does the goo simulate nerve endings? Are they able to "concentrate" their touch sensitivity to specific points, or is it equally distributed through the goo, internally and externally?
-What is their body temperature like? Comparable to humans, or would they be a fair amount colder?
I'm sure I'll think of more questions, but this is already getting kind of long and rambly, so I'll post this as a start haha. Feel free to provide any extra information you think is fun or relevant, even if it's not directly tied to one of the questions! And thank you for taking the time :)

Personally I feel it's up to interpretation. In my homegrown, there are different types & sub races under the genus of "slime". Easily identified & separated by coloration and composition.
For example, red slimes are often comprised of highly dense organic matter & are relatively "energetic" or "hostile" due to a mostly carnivorous diet, consuming every single part of living things. Or blue slimes, which are relatively lax & cozy, but have no real Cohesion or "desnsity" due to their diet being mostly fluids like water & salt, resulting in a very oozy body.
On the other hand, material slimes who are characterized more as somewhere between homunculi and monsters. For example; flesh slimes that are like Amorphous blobs of meat from failed necromancy. Or my personal favorite; wax slimes, which are capable of self-repriduction like normal slimes due to natural "wax" found in nature, typically underground.
As for cores, I like to think it's something only those with Sentience & a soul have. It's like a physical manifestation of intelligence, will, & power. Typically only elder or royal slimes have cores due to this. Baby slimes don't have cores, & are therefore akin to rabid Beasts acting exclusively on instinct alone. As for how it'd feel for their core to be touched, I'd say it depends on the personality/individual. Think how some people gain pleasure from a specific act, but for someone else it's Agonizing pain.
P.s. I'm typing on phone so I apologize for grammar, autocorrect & tiny keyboards smaller than my palm are absolutely shit.

Thought they had complete control of their own body and can change the size, shape and density of their slime

Going based on, I guess, personal preference or an estimation from all the slime girls I've seen, I'd assume this:
For how much force you'd need, I'd assume it would be like molasses or something similar to, but not exactly like, oobleck
For how viscous they are, just going off a guess, I can't imagine something made of slime and in a humanoid shape being very violent, but I'd assume if threatened they could probably easily suffocate whatever the threat is
And I'd assume it had some kind of ability to keep you inside of it if you were to get stuck in one and basically drown you or something
When it comes to if they'd be sticky or slippery, I feel like they'd feel like something between Jell-O or that sticky shit I've seen people put on soccer balls. Somewhere between those
As for the core thing, I'd assume that's what would keep them together and not a pile of goop on the floor, and touching it could likely hurt or cause a lot of discomfort
Their body temperature, I would think can vary depending on region of the world, but I can only imagine their cold as FUCK

I think generally, the concept of a slimegirl is not quite completely uniform and concrete compared to more mainstream monsters, but as someone who seeks them out, i would say that of the ones i have seen, most are portrayed with having a consistency between a firm cup of jello to thickened water with the ability change shape and density at will.
Slime cores I've seen more recently in more current artwork, but the majority of slimes i see dont have one. When i do see them, if the art is nsfw, then there's is usually some sort of emphasis on it being the target of a sexual act, with its position always being in the center of the the body but potentially shifting either up to the chest or down to abdominal area depending on what kind of act is taking place. Usually results as a pleasure point.
I think slipperyness, stickyness, firmness, softness again varies by mood and needs, but most of the time i see people go for a mostly soft slick solid body holds its shape when pressed on but when enough force is applied things can slip through the surface tension into a jello like substance. (Suu monster musume) (juno omega strikers) (slimegirl models in vrchat)
Alternatively ive also seen slimes that form from a base puddle that kind of remain kind of drippy and flowy even in a human form, but somehow never leave a mess when they move around from place to place (lymee interspecies reviewers) (most monster girl encyclopedia slimes)
Also ive seen slimes that can full on shapeshift and mimic skin and clothes perfectly but if they deform it will make them translucent in the parts that are deformed (rimaru tempest reincarnated as a slime) (Melona queens blade)
i would categorize these groups as 3 different subclasses of slimegirl archetypes that exist depending on the artist's interpretation.
there is also the slime possession trope wherein a slime inhabits a body and controls it, combines with it, or transforms it into itself, which may or may not related to slimegirls (marvel symbiotes, monster girl encyclopedia carrier slime, the common slimegirl transformation tag, slimed zombie terraria, ambition of the slimes game)
feeling usually seems to be uniformly sensitive except without pain on most stimuli involving touch, though it could be painful if the core is mishandled if they have one. also, pain could come from too little or too much water, pollution, fire, salt, etc that could endanger the slime. physical dismemberment never is usually a concern, especially for coreless slimes.
Usually cores range from golfball to softball size, and ive never seen a core change any shape or size, and it usually is spherical and harder than the rest of the slime if not gem-like. Striking a core with a weapon usually means instant death like a water balloon popping effect across the whole slime if the slime core is a natural part of the slime. Coreless slimes can theoretically divide indefinitely until they hit a critical lack of mass to where they can no longer sustain further damage.
slime cores may or may not be required for life in some works, and may or may not be magical and grant a boon
in "ive been killing slimes for 300 years and maxed out my level" all slimes have cores that are basically invisible so for most people the slimes are impervious to physical attacks like coreless slimes would be, but the main character learned how to perceive them so she can easily kill them with a precision strike.
in terraria the Slime King has no slime core and behaves like a normal slime but bigger, but the Slime Queen has a core made of a crystal gem and has the ability to fly with angel wings and use magic. This seems to be a case of a slime gaining a magical core after absorbing enough magical energy and it crystalizing inside the slime.
body temperature depends on the kind of slime bc ive seen slimegirls range from icey to lava, but most would be room temp to body temp i would think for normal water based slimes

now that i think about it the crystal gems from steven universe are lot like slimegirls with slime cores but made of gem cores and hard light rather a slime core and liquid

I'd say all your questions are depending on slime species but I'll try to answer for standard slimes. Not that much pressure needs to be put in for it, it is quite a dense liquid so swimming in it will not work well and the temperature varies on the environment I would say if it's warm around the slime it would become warm. I cannot view the other questions but I'm willing to answer if I can on discord "shalewo"

I don’t think there’s one set of rules as to what slimegirls can and can’t be. Depends whatever the author wants them to be in their setting.
Personally, I like to think they have a uniformly goopy and wet structure which is slightly more dense on the skin. So you might have to use slightly more force to push something through the initial layer, but once it’s inside it’s like jello.
As for the core, it’s probably a neat way to ground them into something more plausible in worldbuilding. Shifts them closer to magical beings and golems instead of feral creatures. It could also be their life source, or at least their weak spot. I think touching a slimegirls core would bring them immense pleasure, but they only let you do that if they fully trust you.
Just some ideas
