Created as a helper for showing the family jewels below underwear, jockstraps, shorts, etc, since I haven't found a FLUX base model that can do it out of the box. Inspired by a Pony version from Rokudenashiworshiper

It shouldn't need a trigger word so long as you are descriptive in your prompt but 'ball cleavage' or 'testicle peek' should help... that and increasing weight (0.8 - 1.0 usually works fine)

I created it for an inpaint helper but it can generate full images of the concept on its own fairly well, although depending on the checkpoint probably would require a 2nd img2img inpaint pass masking over any body horror using the original prompt or region specific prompt.

TL;DR: So if the checkpoint your using can't create a dong and nutsack on its own don't expect this thing to do a full image generation 1st pass miracle run. Instead, it likely require a few attempts on a txt2img run or better yet use it for an img2img inpaint helper.

For a more realistic effect, dial down to around 0.75 strength which should solve any body horror/artifacts.
