The cagina is very rare but is common in Asia. It is when a males penis is either inside their body making a slight vagina, or is simply too small to recognize as a penis. Occurrences with female is when a female adolecence has an orgasm that solidifies and cannot be torn off the vagina and then gets a orgy-penis.
