Why do people often masturbate at the age of 12 and 13?

Patient's question:

Patient gender: Male
Patient age: 28
Hello, this condition is normal and does not fall under the category of micropenis. If you are not satisfied, you can opt for surgery to lengthen the penis. The principle of penile elongation surgery is to make the penis corpus cavernosum, which is buried in front of the pubic symphysis, a free part (i.e., to release it from being buried).

Doctor's answer:

Hello, this situation is normal and does not fall under the category of micropenis. If you are not satisfied, you can opt for surgical lengthening. The principle of penile lengthening surgery is to make the buried corpus cavernosum, which is hidden in front of the pubic symphysis, a free part (i.e., pulling it out). Approximately 3-5 cm of the buried corpus cavernosum can be freed at one time, thereby increasing the effective length of the penis by 3-5 cm. It is recommended to visit a regular specialized hospital for a face-to-face consultation to determine if you meet the surgical criteria.
