v1.0 for SDXL for Pony Diffusion v6:

Same number of images with the same tags (needs to be reworked in the future, will certainly help) but trained on Pony Diffusion v6, you can't use it on models that aren't derived for Pony Diffusion, also use the same parameters as for PDv6.

v1.7:

Same number of images but better tagging and parameters, everything feels good now and I don't really need to improve it (except actually making it leave the body)

Tags triggering:

onahole: basic trigger words
onahole excretion: making the onahole
onahole excreted: the onahole left the body but the orginal body is still in the image
slime girl//flesh onahole//slime girl+flesh head: texture of onahole
holding onahole/sex/cum inflation: for specific actions, can be combined
{insert color, eg: pink, blue, red, orange...} skin: in combination with slime girl
transparent onahole: works sometimes but depends heavily on the model and on luck
legsless/armsless/headless: control the body shape*

Notes

I seems that putting a high transparent weight (transparent onahole:1.5) put them in boxes, like at a store so it is really good for selling and exchanging them.

v1.2:

Slime/Flesh differentiation is better, personality excretion/excreted is better, I tried to add a translucent tag (37 images have this tag) but without much effect (see-through and x-ray is hard with SD).

Headless onahole doesn't work at all even with high anti head in the neg-prompt, I think that models are trained way too much on faces, If anyone can generate without heads don't hesitate to post it

So this is the final model with this number of images.

Tags triggering:

onahole personality: basic trigger words
personality excretion: making the onahole
personality excreted: the onahole left the body but the orginal body is still in the image
slime onahole//flesh onahole//slime onahole+flesh head: texture of onahole
holding onahole/onahole penetration/cum inflation: for specific actions, can be combined
colored skin, {insert color, eg: pink, blue, red, orange...} skin: in combination with slime onahole
translucent onahole: doesn't work in higher strenghts
legsless onahole/armsless onahole/headless onahole: control the body shape

v1:

I'm back for my second model, its goal is to generate living onahole that are created through the excretion of their personality, The first version is not yet stable but I'm already working on an updated version with better tagging that will hopefully improve the versatility of the model. I'm uploading this one since it is largely usable.

Tags triggering:

personality excrement, onahole personality: basic trigger words
personality excretion, object insertion: making the onahole
slime onahole//flesh onahole//slime onahole+flesh head: texture of onahole
holding onahole/onahole penetration/cum inflation: for specific actions, can be combined
colored skin, {insert color, eg: pink, blue, red, orange...} skin: in combination with slime onahole

Problems:

More often than not the tags are mixed together and the slime/flesh differentiation is hard depending on the model.

Different body parts can appear out of nowhere depending on the model.

My goal with the cum inflation being visible through the skin is not done properly.
