Call me MOTI, but the Amhole is not a vagina. Women don't have wounds that they constantly have to keep open to prevent their vaginal canal from collapsing on itself (although, some women do dilate due to vaginismus or other conditions). Women have the parts and glands to create natural lubrication, and their hips are in such a way that helps with childbirth. Sure, I guess there are other TRANSGENDER women who have "vaginas" (just like how TRANS men can have "penises" and "testes"), but they don't have the full reproductive system like cisgender women do, they'll never have a menstrual cycle, ovaries, a cervix, etc.
