The penis length is normal.

Penis length varies from person to person, and there is no fixed standard. Penis length is generally between 7-16 cm when erect.

Penis length is determined by many factors, including genetics, race, age, nutrition, etc. There is no direct relationship between penis length and sexual function, sexual satisfaction, etc. Under normal circumstances, penis length is between 7-16 cm when erect.

If you are not satisfied with your penis length, you can try to improve your self-confidence and sexual satisfaction by changing your lifestyle, increasing exercise, improving nutrition, etc. However, please note that these methods may not significantly change penis length, so please keep a rational and objective attitude.
