you can tell they’re not actually British because in Britain people who have “willies” do not have “fannies”
Penis preserving vaginoplasty is a thing. I don’t think it’s at all common but it is a thing
Considering that the peen is propped up by the part that continues inside the taint, either the dick anatomy and functionality isn’t quite entirely preserved, or the vagina would have to be plasted above the dick. 🤔
I think it just uses the canal that’s already there if you don’t opt for zero-depth. Not sure how functional the vagina is though, but iirc the penis functionality is usually preserved.
Considering the extent of corpus spongiosum, part of the root of the penis, I don’t see how you could shove it aside and put a hole and the vulva in there. Except if it’s some kinda microvagina.

Two words: inguinal canal.
Though that would still be awkward, as it would mean the new vagina’s off to the side instead of in the middle.
Not saying it’s for sure how it’s done (I have no idea on that), just that I think that’s the “canal” OP is referencing.
TIL futas are real
Mmm, I would not recommend using that word when talking about real people
