My take on horse pussy. My opinion might not be valid so don't take it seriously. It all depends on person's aesthetics to judge the way how to portray beauty.
not provided yet
Horse pussy does normally open like a wallet, but it's the vulva that open, not the butt cheeks. It's normally a tiny little tightly closed slit following the curve of a belly back there, generally covered up by tail. From the side, the foreground butt cheek does usually obscure the vulva and anus, so they can only be seen from close to directly behind. You can draw whatever you want of course.
When in doubt, look at a photo.
How else do you think they buck trees all day? On a more serious note, a compromise is more likely, where the parts are "reasonably sized" and aren't very visible unless directly behind. Also pony vaginas/sheathes already act like "wallets" and aren't considered indecent unless winking/erect.
