Amethyst said that he likes the feeling of food going througt her body, so she had to shapeshift an anus in order to defecate.
Food probably would just came out as food instead of poop since she doesn't need the nutrientsI know it's a cartoon but I'm pretty sure the crewverse has the right answer for this since they are huge nerds about talking this kind of shit.
My take is
amethyst: has a vagina, looks pretty normal.
pearl: no vagina
garnet: no vagina. most people would think she has one for masturbation (since it would counts as sex) but fusion itself is sex for her.
