 I myself haven't entered the Crimson Cavern, but from a fresh perspective, some of you aren't thinking about this enough. These points are in order of reasonability.

 1) If you were buried to the neck, you wouldn't be able to move. If Cthulhu was x times larger than you, the pressure on it would not be x times stronger: his sheer surface area would make the pressure multiply exponentially. Millions if not billions of tons of pressure would be exerted on it.

 2) Cthulhu could still be dormant and petrified, if only partially. When organic matter is submerged for millennia, minerals leach into the matter, fossilizing the remains. No animal has lived long enough, much less survived the extreme pressures, to be fossilized alive. Regardless of this, the immense pressure would no doubt constrict blood flow (much like when our limbs "fall asleep"), except to the point the for all intents and purposes, Cthulhu's exterior is dead. There is no reason except magic that fossilization wouldn’t occur, although it would happen at a slower scale.

 3) This game has magic, and someone has been here. In most magic realities, what came before was stronger. Imagine: you’re digging around and find a golden chest with a spell in it. The only reason they would have left that spell is because they had something better. The heroes/rogues of the surface Dungeon for example: They had the magic skill to keep one man alive long enough to find him, turn him into Skeletron, turn him back, and summon the Dungeon Guardian if you try to sneak around the trial (yes, they want someone to enter the Dungeon), as well as animate their bones. They were probably the ones who imprisoned Cthulhu in the first place. If so, then perhaps Cthulhu cursed them all in such a way to spite them. This “Old Magic” theory is further supported by   "The ancient spirits of light and dark have been released" and the Ancient armors. They are Shadow and Cobalt: one the best Pre-hardmode armor without going to hell (also, someone lived in the Underworld besides the demons and imps, and they had dolls), the other the next step upon entering Hardmode.

 4) This game is highly reminiscent of Norse mythology with the dead vikings, giant tree(s), and multiple worlds. When the Norse gods killed the first being, Ymir the Frost Giant,  "From Ymir's flesh the earth was formed, and the rocks from out of his bones; the sky from the skull of the ice-cold giant, and the sea from his blood."

 5) This is a game, and as such the creator(s) has the right to creative license and can create, use, and combine his/her original ideas with common lore and old ideas. The description doesn’t have to match records of Cthulhu for Jboy91’s theory to be correct: It depends on what the creator intended to create. It is obvious to me that the Crimson Caverns have cave entrances (with teeth, I have seen those) opposed to deadly trenches that you die on impact if you fall into for a reason. I imagine the creators put much more thought into the Crimson than the Corruption to make a brand-new, challenging experience for the gamers to play, wonder at the origins of and have intelligent discussions about. I think your theory is sound Jboy91. Good job! Now I feel like I’m on Game Theory or something.
