perineum

n. area of the body between the rectum and the vulva or penis (Anatomy)

In human anatomy, the perineum, also called the "taint", "grundel" or "gooch", is generally defined as the surface region in both males and females between the pubic symphysis and the coccyx. A diamond-shaped area on the inferior surface of the trunk which includes the anus and, in females, the vagina. Its definition varies: it can refer to only the superficial structures in this region, or it can be used to include both superficial and deep structures. The perineum corresponds to the outlet of the pelvis.
