Definition of Vaginal opening

Vaginal opening: The opening to the muscular canal extending from the cervix to the outside of the body. The word "vagina" is a Latin word meaning "a sheath or scabbard", a scabbard into which one might slide and sheath a sword. The "sword" in the case of the anatomic vagina was the penis. Love and war, it would seem, have been connected in the minds of people for millennia.

The vaginal opening is called the vestibule of the vagina. In medicine, a vestibule is a space or cavity at the entrance to a canal, channel, tube, vessel. In ancient Rome, the "vestibulum" was an entrance or enclosed porch leading into the house.
