Okay, one last comment before I wear out my welcome: this is actually super fascinating. The reason for this difference has to do with genital homology[1]. Basically, apart from the vagina itself, almost every part of male and female genitalia is made of the same essential “stuff”, just smooshed around to suit different roles. Crucially, all the most important nerve endings are there— so if you rearrange stuff to be in more or less the right place, you get something that works more or less the way you’d expect. The only issue is, if you got the deluxe variety pack at birth, you probably have a bunch of extra “vulva skin” that you don’t really need, and it’s hanging out in just the right place to make a neovagina out of. Neat! But if you’re stuck with the original flavor, you’ve probably only got a tiny little bit of “penis muscle” to make do with, so you have to get much more creative.
