That's actually a look for external bits of vaginas. It's called an innie pussy. Semi rare but not unheard of, had an ex with one actually lol. Not only do I prefer the look but it's also easier to manage for stable diffusion generations. Lighting is intentionally soft on these too, never liked the look of sharp lighting in porn, too "professional" Thanks for the feedback regardless lol, I might post some more with outie pussies at a later date

I guess I'll be nice and share prompts lol. Something along these lines, although each were tweaked somewhat.

Model used is photon v1, upsclaler was NMKD superscale 4x, steps 20, high-res steps 15, cfg scale 5, sampling method DPM++ 2M Karras
