Kink content, don't like don't read (AKA scroll past)
There's just a few of these, but the post seems long to me for some reason, so I'm putting a read line. Satisfying the inner formatting desires.
[1] It's been a while since I last looked at Albedo content, so I'm not entirely certain if it's ever mentioned if he does actually need to eat, despite being made of chalk. However, one thought that's been lingering in my head for the longest time would be Albedo drinking water.
Just like with food, I'm not actually certain if he needs to drink water/liquids at all. However, I do know that chalk is soluble (aka it dissolves) in the vast majority of consumable liquids, and that it bubbles and produces CO2 when it does dissolve. As such, when he does eventually drink something, I imagine that Albedo would soon just be left with a vaguely uncomfortable, bubbly feeling in his gut as the liquid causes the chalk of his stomach to slowly dissolve. Plus, maybe he'd get gassy because of the aforementioned CO2 production and bubbling.
In general, I can't imagine it'd be a particularly comfortable experience (although an interesting one to study - one he'd probably conduct a few times, to locate differing variables and causations).
[2] He's the Chief Alchemist. Sometimes, things go wrong or unexpectedly in alchemy(/science). Considering the amount of time* he spends alone(?) up in Dragonspine or elsewhere, it would be reasonable to assume that sometimes the only subject for him to test with is himself. As such, if something turned out wrong with something designed to be consumed, he'd have to deal with the consequences it has on him, himself.
*Long enough that there's note of it taking time for him to return.
Additionally, there is the simple factor that he is a homunculus, so formulas that may react alright with humans could have a much more intense reaction on him (or vice versa).
(However, on an inverse situation, I would like to remind you on the canonical experimentation done with the Traveller)
[3] Perhaps it's a bit basic, but I think he'd struggle somewhat with burping. You know when it feels like a burp is stuck in the base of one's throat? Yeah, that.
[4] Ignores his stomach's rumbling when it's not inhibiting his ability to move or do anything. Perhaps it's noisy, but it's not holding him back any from continuing with his work.
It takes other, truer humans around him, getting food typically at the first noises, for him to eventually, occasionally acknowledge and appease his stomach early into its vocal expressions.
[5] Noisy tummy specifically when hands are laid on it. Others or his own, hungry or full, it's basically a guarantee that whatever noise was being made by his stomach before pales in a volume comparison to when it's being touched.
you're not pressured by society to get in a relationship, you're pressured to be in a HETEROSEXUAL relationship. There's a difference. :) stop acting like you're the only ones affected
