The foreskin cannot cover the glans, it is exposed for a long time, is it normal?

Patient's question:

Age
Detailed medical history and purpose of consultation: At the age of six, due to tight phimosis, the glans could not be exposed, affecting urination, and a circumcision surgery was performed. After the surgery, the foreskin cannot cover the glans, and it has been exposed for a long time. Is this normal?
Duration of the current illness and persistence:
Current general condition: No pain, long-term exposure.

Doctor's answer:

Generally, before the onset of puberty, the penis is mostly covered by the foreskin. Around the age of 7-10, puberty begins, and the penis starts to grow rapidly, reaching adult size within about 3-4 years. As the penis grows longer, the foreskin naturally retracts, gradually exposing the penis. Under normal development, when the penis is flaccid, the glans can partially protrude, and when erect, there is no excess foreskin. If the glans does not protrude when the penis is flaccid but can fully protrude when erect, this is also considered normal. Only when the glans cannot fully protrude even when erect (but can be fully exposed by retracting the foreskin) is it referred to as phimosis. For simple phimosis, as long as local hygiene is maintained regularly, it has little impact on sexual life. If the foreskin opening is narrow and the glans cannot protrude at all, it is called paraphimosis. Paraphimosis often accompanies phimatocele, which not only makes hygiene difficult but can also cause pain and discomfort during marital life, even affecting the health of the sexual partner. Solutions include surgery. Surgery can be performed at any age. However, since daily bathing is required during hot summers, it is best to avoid surgery during the autumn and winter seasons to prevent contamination of the wound and infection during bathing. The other solution is self-stretching of the foreskin opening. This involves regularly retracting the foreskin from its flaccid state, allowing the foreskin opening to gradually widen as the glans becomes congested and erect. If this is done around the age of 10, it is most effective (fathers are particularly urged not to overlook this). Some adhesions may also separate, causing mild pain and bleeding. Usually, there is no significant bleeding, as adhesions only exist on the superficial mucous membrane. In the past, when medical conditions for surgery were not available, men with paraphimosis would undergo this process.
