1 The medical definition of foreskin is that in a weak state, the glans penis cannot be exposed by two thirds, indicating that the foreskin is too long, but if it can be exposed by half clinically, surgery is not needed.

Your current situation is that your foreskin is too long. If you can't get rid of it completely after erection, it belongs to phimosis and needs surgical treatment.

Let me talk to you about the harm of too long foreskin. Too long foreskin refers to a layer of soft skin outside the penis head. Infants and young children have a long foreskin and a small opening, which can protect the delicate glans outside the penis head. With the increase of age, the foreskin gradually retreats behind the penis head. In adolescence, the foreskin turns up naturally with the development of genitals, exposing the entire glans penis. If the foreskin still completely wraps the glans penis in the stage of youth development, it is called phimosis; If it can be turned up, but the glans of penis can't be exposed frequently, it is called "foreskin is too long". Excessive prepuce and phimosis are common diseases among male adolescents. However, due to the lack of knowledge of teenagers and the neglect of parents' guidance, it is easy to be ignored. If teenagers have problems such as too long foreskin and phimosis, and usually do not pay attention to hygiene, it will lead to a series of diseases, which will also have adverse effects on married sexual life and fertility.
