Hinder penis development: affect sexual harmony: phimosis will affect penis growth and development. In adolescence, because the penis head is tightly wrapped by the foreskin, it can't be stimulated by the outside world, and the development of the penis head is greatly inhibited, which leads to the obvious reduction of the circumference of the penis head and crown 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. c
