A prolapsed vaginal wall or vault is the result of a variety of things.
Age
As women grow older the natural strength and elasticity of the internal vaginal connective tissue weakens. This can cause the interior of the vagina to drop or fall out through the opening.
Childbirth
In some cases a prolapsed vagina is the result of continual child birth. The loosening of the interior of the vagina from multiple pregnancies in a relatively short period of time can occur. When the interior of the vagina is not allowed adequate time to shrink and tighten before being stretched by another birthing.
Fisting/Sexy Toys/Large Penetration
On average the most common cause of a prolapsed vagina comes from extreme penetrations. When a woman is penetrated by large penises, sex toys or fists (or other objects) continually on a regular basis, the interior vaginal tissue becomes loose and has a higher risk of prolapsing out through the opening.

The inner vaginal wall is lined by stratified squamous epithelial cells. These cells are layered and flat in shape, which helps protect the vaginal wall from friction and damage.
Sounds like some sort of STD, I suggest going to the doctor to find out what it is and have it treated.
Colporrhaphy, usually done by pulling together the weakened area of the vaginal wall with sutures.
Prolapsed translates "inside out." (More or less). So when your guts "fall out" of a wound, that would be an example of a prolapsed wound.
