Location of the Male Perineum

The male perineum is a highly sensitive area that plays a crucial role in various bodily functions, including urination, defecation, and sexual activity.

Located between the anus and scrotum, it is a diamond-shaped region approximately 4 centimetres wide and 6 centimetres long, or most visibly, the area adjacent to the perineal raphe.

The perineal raphe is the relatively symmetrical ridge of skin between the anus and urethra, i.e. the holes where faeces and urine leave the body.

The perineum is bordered by the pubic symphysis (the joint at the front of the pelvis), the coccyx (the tailbone), and the ischial tuberosities (the bony protuberances on either side of the buttocks).

The perineal region has several important functions and serves as a crucial anatomical landmark.

Structure & Function

The male perineum houses the external genitalia, including the penis and the scrotum, which contain the testes. These organs play a critical role in the male reproductive system, producing and storing sperm.

The perineum comprises several important muscles; the external anal sphincter, levator ani, bulbospongiosus muscle, ischiocavernosus, transverse perineal muscles.

These muscles are responsible for controlling bowel movements and urination, and also play a crucial role in sexual activity.

The male perineum is also essential for maintaining the overall health of the body. It is rich in blood vessels and nerves, and it plays a crucial role in maintaining proper blood flow and nerve function in the pelvic region.

Finally, the male perineum also serves as an important anatomical landmark. It is the site where several important structures converge, including the urethra, the anus, and the prostate gland.

This makes the perineum an important location for medical procedures, such as prostate exams and the insertion of urinary catheters.

The Male Perineum & Sex

On a male, the perineum provides strong structural foundation for the penis and scrotum. It is highly enervated and an extremely sensitive erogenous zone.

The perineal region also contains the bulb of the penis, which is a spongy erectile tissue that fills with blood during sexual arousal. The bulb of the penis is surrounded by the bulbospongiosus muscle, which contracts during ejaculation to help expel semen from the urethra.

The underside erectile column of the penis, or corpus spongosium, extends far back into the body and is directly cradled by the perineum.

During erection, the entire area swells as the corpus spongosium pushes hard against the perineal muscles, particularly the bulbospongiosus.

This ideal hyper-erotic state helps ensure a powerful climax as the cremaster muscles lift the testicles to brace against the penis and perineum prior to ejaculation. Digitally stimulating the perineum during ejaculation waves can significantly prolong and intensify the orgasm.

The perineum also contains the anal sphincter muscle, which plays a role in sexual function by contracting during orgasm.
