Penis captivus allegedly occurs when a penis becomes stuck in a vagina during sexual intercourse. Reports of this happening are incredibly rare. Very few reports have documented the existence of penis captivus. What reports there are have led many people to question whether it really happens. The penis becoming stuck in the vagina is one possible outcome of a condition called vaginismus , in which the vagina involuntarily closes due to muscle spasms in the pelvic floor. If penis captivus occurs, the effect is likely very temporary.

In fact, the depth of the vagina from the opening to the tip of the cervix can measure anywhere up to 7 inches Several types of tissue line the inside of the vagina, including the mucosa. The mucosa is made up of specialized cells that secrete a lubricating fluid, which helps the vaginal walls to stretch. The exterior portion of the female genitals is the vulva. The vulva includes the labia minora and majora — the lip-like parts of the female genitals. The appearance of vulvas varies widely.
