The Bladder Vee-String Female Vagina ProsthesisTM is designed to fulfill the feminine illusion. Your penis is placed into a hole in the bladder, which holds you in place. The bladder does not hold liquid, but allows for an even flow. This allows urination in a sitting position as a female without removal or adjustment.
This does not have a vaginal sheath or menstrual function. If you want one or both of those functions, you may order a Sheath, Sheath with Urinating Bladder, or Masturbator with Sheath Vee-String.
