Perineum

He was attacked with complete retention of urine, after a debauch, and six weeks afterwards an abscess formed in the perineum, which eventually burst, leaving a fistulous opening, through which the urine continued to be discharged to the period of his admission into the Hospital.

The prostate is surrounded by venous plexi and the perineum has a rich blood supply.

The perineum is diamond shaped and stretches from the pubic symphysis to the coccyx.
