Penis hood is too long, penis is too small.

Patient's question:

Patient Gender: Female
Patient Age: 28
I am 18 years old. My foreskin completely covers the head of my penis, and when I am not erect, my penis is about 3 to 4 centimeters long, and when erect, it is about 11 centimeters long. It is also a bit thin. What is the matter?
History of Treatment and Effect: None

Doctor's answer:

Under normal circumstances, an erection of at least eight centimeters does not affect sexual life. According to your condition, if there are no symptoms such as weak erection, impotence, or premature ejaculation, it is normal. You can increase it by strengthening exercise.
