A synthetic vagina made from the scrotum or penis tissue, usually from a transsexual seeking gender reassignment. The testicles are removed from the patient, and then either the penis skin is pushed up inside of the person, or the ballsack is made into a vaginal cavity. Vulva, clitoris, and labia can be fashioned from penis tissue.
Now that I am a freshly minted woman, my male partners can stick their junk in my fauxgina. It may not be real, but it is spectacular.
