This is a very male, penis-centric POV. Coz all the talk about these surgically-created fauxginas being "functional" only considers whether they are fuckable. And all the claims that these surgical creations "feel like" the real thing come from the POV of males who want a fauxgina, or want to stick their dicks in one.

But the human vagina is not merely a fuck hole. It's the birth canal by which women bring new human beings into the world; it's the organ that enables most conceptions of new life to occur; it's the outlet for menses; it's an organ that plays crucial roles in maintaining the health and wellbeing of the female reproductive tract.

The vagina is a muscular organ that can push real live babies into the world, and it has to expand many, many times its normal diameter to do this. This is a far cry from being merely a little bit stretchy to receive a penis or dilator like peritoneal skin used in fauxgina surgeries is said to be. The very fact that guys with fauxginas made of any material need to regularly dilate is proof that their surgically constructed pelvic sleeves are nothing like actual vaginas.

The vagina is lined with unique tissues/mucous membranes containing tens of millions of proton pumps that make it not only self-lubricating, but continually self-cleaning. The vagina has unique biochemistry and flora. Regardless of what tissues are used, surgically constructed fauxginas have none of these characteristics. On the contrary, they have been found to have flora and biochemistry that are consistent with chronic bacterial infections rather than with actual vaginas.
