Excessive foreskin affects sexual life. 1. Obstructs the development of the Yin Meridian, and too long foreskin will affect sexual life: phimosis will affect the growth and development of the Yin Meridian. In adolescence, because the head of Yinjing point is tightly wrapped by foreskin, it can't be stimulated by the outside world, and the development of the head of Yinjing point is greatly inhibited, which leads to the obvious decrease of the crown circumference of Yinjing point after the sexual organs mature, which affects sexual pleasure. Adults will affect their normal sexual life because their foreskin is too long or phimosis. Especially for men whose foreskin is too small, it can't be recovered after the foreskin is turned up, and the foreskin is tightly stuck in the coronary sulcus, forming incarcerated phimosis, which is not very painful. In severe cases, the glans penis will be edematous due to poor blood flow, and even the glans penis will be necrotic. 2, there is a risk of cancer: the foreskin is too long and phimosis may induce vulvar cancer. Modern scientific research shows that echinococcosis is a carcinogen. According to the survey, 85%-95% of patients with vulvar cancer are phimosis or redundant prepuce. Too long phimosis and foreskin not only affect health, but also bring scale into vagina, stimulate uterus and induce cervical cancer, which is also the embodiment of the influence of too long foreskin on sexual life. 3. The influence of long foreskin on sexual life is also reflected in the damage to renal function: due to vulvar inflammation, the urethral orifice or anterior urethra can be narrowed, resulting in dysuria. Long-term dysuria will damage the function of the kidney. 4. Inflammation of the Yin meridian: There are rich sebaceous glands in the foreskin, which can secrete a lot of sebum. When phimosis or foreskin is too long, the secretion of sebaceous glands in foreskin can not be discharged, and the sediment in sebum and urine synthesizes cheese-like odor. Skin scales are suitable for bacterial growth, so they can cause inflammation of the vaginal head and foreskin. Bacteria can also cause urinary tract infection through urethra. Inflammation at the urethral orifice can lead to stricture of the urethral orifice after healing, resulting in dysuria.
