Well, I was a nurse's assistant for twenty years, and had female patients in ages ranging from infant to 103. Sometimes, someone poops and you have to get in there and visually confirm everything is clear.

I never once saw vulvae like that. Never have in pornography, erotica, or with sexual partners.

As art it's fine. Nothing wrong with interpretation of reality. But as an anatomical model, it fails horribly.

For one thing, no clitoral hood. No urethra that I can see. Even assuming the near infinite variety of shapes labia can be, and assuming that a person only has labia as depicted, there's still a lack of other anatomy that would be easy to visually verify for something intended as an anatomical reference.

Tbh, it looks less realistic than some of the stuff I saw on bathroom walls in high school lol.

Even pictures I've seen of genital mutilation, voluntary body modification, and post surgical results don't look like that.

I think the closest I've seen was post labiaplasty, when everything was still swollen enough the lady couldn't close her legs without pain.

I just don't believe the artist used any model at all.
