This article may require cleanup to meet Misplaced Pages's quality standards. The specific problem is: Needs better sourcing, is this really a structure in its own right, or just a different name for the perineal body? Term seems to have originated in one book; see talk. The sex stuff in particular needs WP:MEDRS. Please help improve this article if you can. (December 2024) (Learn how and when to remove this message)

The perineal sponge is a spongy cushion of tissue and blood vessels found in the lower genital area of women. It sits between the vaginal opening and rectum and is internal to the perineum and perineal body.

Functions

The perineal sponge is composed of erectile tissue; during arousal, it becomes swollen with blood compressing the outer third of the vagina along with the vestibular bulbs and urethral sponge thereby tightening the vagina and increasing stimulation for the vagina and a penis, if involved.

Sexual stimulation

The perineal sponge is erogenous tissue encompassing a large number of nerve endings, and can, therefore, be stimulated through the back wall of the vagina or the top wall of the rectum.
