Probably should use AutismMix SDXL.

Must use selfarmpitlicking, licking own armpit

Might be able to use one arm raised to only raise on arm, but I recommend not doing poses that are too complicated, or else your anatomy will look unnatural.

Trained on Pony XL. Hands do not look good, so it's better if they are hidden. Shoulder is also sometimes bonked. Tongue is sometimes too long or doesn't reach the armpit. There is also not much variety in the poses, but finding training images for this concept was difficult.
