Men generally don't care whether their foreskin is too long. They feel that as long as it doesn't affect their sexual life, it doesn't matter. In fact, this idea is wrong, because if they really have too long foreskin, it will bring a lot of pain and disease to their future sexual life and penis, so men must not ignore it.
The prepuce is too long because the glans is inside the prepuce when there is no erection at ordinary times. If the prepuce not only covers the whole glans, but also the prepuce mouth is narrow, the prepuce cannot be turned out. This state of medicine is called phimosis. Whether the foreskin is too long or phimosis, its characteristic is that the foreskin covers the glans and urethral orifice for a long time, so that the mucus secreted by the glands in the inner plate of the foreskin, the urethra, the coronary groove and other parts cannot be discharged and accumulated in the foreskin. With the "irrigation" of urine, the foreskin and the local area of the coronal groove become a good breeding area for bacteria. Those secretions and the organic components in urine become the natural "grain depot" of bacteria. The bacteria multiply and thrive in the fertile breeding bags with appropriate temperature and humidity, and occasionally "make waves" in the local area. Especially in summer, when the gland secretion of the human body is vigorous, it just provides sufficient nutrition for the bacteria, and the bacterial family also thrives.
The foreskin often wraps the penis, causing inflammation of the glans. For example, it causes glans foreskin inflammation, which is characterized by local redness, papules, ulcers, etc. Some patients develop into the human body in depth along the urethra due to bacteria, which can invade the prostate, seminal vesicle, epididymis, testicles and other male reproductive systems. Especially for patients with phimosis, a large amount of secretions cannot be discharged, and deposition can form foreskin scale. Children with phimosis often see concave-convex "bumps" on the foreskin surface. These "bumps" are foreskin scale. Because the long foreskin creates a good place for the survival and incubation of bacteria, the anti-inflammatory treatment is difficult to complete. It is often "a single spark can set the prairie ablaze again", leading to the recurrence of foreskin balanitis. Some patients have experienced balanitis for decades, and long-term and chronic stimulation of glans epithelial cells, eventually due to the transformation from quantitative to qualitative change, penile cancer occurs and endangers life. The harm of long foreskin to human beings cannot be ignored.
