I have a friend who is only 14 years old. Sometimes he masturbates, and now his private parts have turned black.

Patient's question:

Darkening of the genital area, left labia are larger than the right, labia minora inversion

Doctor's answer:

Hello, according to the situation you described, teenagers of your age are in a critical period of development. At this time, it is not advisable to engage in masturbation to avoid certain gynecological inflammation. It is recommended that your friend stop masturbating. Local discoloration is normal and there is no need to worry.
