It is easy to judge that the foreskin is too long. In the state of non-erection, that is, the state of penile weakness, you can try to turn your foreskin over and see if you can turn it over. If the foreskin can be everted and the glans can be exposed, it is not phimosis. If the foreskin can't be everted, the foreskin is too tight, the glans penis can't be exposed, or the glans penis can't be fully exposed without erection, this situation is called phimosis.

The foreskin is too long, which means that although the foreskin covers the glans, the glans is not naturally exposed, but it is easy to evert and expose the glans, which is called the foreskin is too long. Clinically, phimosis must be operated, circumcised or cut by laser, and the glans penis must be exposed naturally.

Otherwise, local infection of foreskin and glans penis will occur repeatedly in the future, and even the foreskin will be scarred and narrowed, which will affect urination and lead to dysuria. More seriously, because the foreskin wraps the glans penis and the coronary sulcus for a long time, it is difficult to do effective cleaning and nursing locally, and there may even be a risk of penile cancer in the end.
