There are two types of penis. One can expand and extend during erection, referred to as grower. While other types, namely shower, looks great all the time but does not increase in erection. A survey from Men’s Health reported that 79 percent of men had penis growers, while 21 percent had a type of shower.

With all the attention spilled in the area below there, we have to investigate, not all men really understand the anatomy of their penis. Familiarizing yourself with your own limbs (yes, including your genitals) is important, because once you see a sudden appearance of anomalies, such as a lump or reddish rash, you first have an initial picture of normal body standards You.
This article provides detailed guidance on penile anatomy that you must know.
What is penis anatomy like?
The penis is the male sex organ, which reaches its full size during puberty. A penis consists of three main parts, base or root (radix), stem (corpus), and head (glans). As the name implies, the root of the penis is the top and most permanent part.
Penis root not visible from the outside because it is located in the superficial perineal sac at the pelvic floor. Roots contain three erectile tissue, i.e. a pair of crus (two feet) on each side that flanks the penis bubble (bulb), and two binding muscles (ischiocavernosus and bulbospongiosus) The surface of the skin that protects the base of the penis usually has pubic hair.
These three erectile tissues radiate along the shaft of the penis. Penile shaft is a long bar that bridges the root with the head of the penis, hanging from the pubic bone. The penis body has two surface sides: a front view that is seen when the penis is "resting", called dorsal, and ventral or uretral (inner side of the stem / testis). Two deep-rooted crura from the base of the penis move forward to form the corpora cavernosa.
Corpora cavernosa are two tubes on both sides of the penis filled with blood during erection. These two tubes are separated by the septum of the penis, although generally not completely separate. In the penile shaft, the bulb forms corpus spongiosum located in the middle. The urinary tract is inside the corpus spongiosum.
The end of the corpus spongiosum enlarges to form penis head cone-shaped, which also binds corpora cavernosa pairs. At the end of the head of the penis lies the urethral duct to remove urine from the body. In uncircumcised men, the head of the penis is coated with a moist, pink tissue called mucosa, which is protected by foreskin skin. In men who are circumcised, the skin of the foreskin is lifted so that the mucosa in the head of his penis changes to dry skin.

Pigments, aka skin dyes, in the skin of the penis are richer than other skin parts of the body. That is why maybe your one-two-tone tones are darker than your belly skin.
What is the process of ejaculation of semen during orgasm?
Ejaculation begins with stimulation. Men see or feel something that arouses sexual arousal. This signal encourages the brain to send nerve messages through the spinal cord to the penis, causing the corpora cavernosa to relax to allow more blood to flow in and fill the empty space inside. This heavy blood flow then creates pressure, so that the penis's body swells and hardens, aka erection. At the same time, scrotum (testicles) are attracted to the body to prepare sweet water and the muscles of the whole body tighten.
Before the semen is sprayed, the mature sperm must first be transported out of the "warehouse", that is epididymis, through a carrier hose vas deferens to be collected at the end of the urethral duct on the head of the penis. During the trip, this fresh sperm cluster passed several important posts, such as seminal vesikulas and prostate each of which secretes a special liquid to thin the sperm and creates the milky white sticky liquid we know as semen.

Semen gathers in the back of the penis head, at the end of the corpus spongiosum. While semen meets the urethra, the pressure from muscle contraction continues to urge more fluid forward. At this time, the bladder automatically seals the urinary opening to prevent the back flow of semen into the body.
The closure reaction of this bladder is also the reason why urine does not come out with semen during orgasm. Because the in and out lane is tightly sealed, the semen that keeps coming in eventually makes the urethra swell twice the original diameter, indicating that the semen is ready to be released. This whole process, called emission, takes three seconds.
Still remember two binding muscles, ischiocavernosus and bulbospongiosus? Together, these two muscles create a pumping force after receiving signals from nerves at the base of the spine to spray semen out of the body at incredible speeds. Some of the first sprays are so strong that they can accelerate half to one meter in the air. The penile muscle will continue to follow this ejaculatory response for three or four times with a strong contraction that continues to slow down.
