21-year-old son, these days noticed the lower part of the penis, when the foreskin retracted

Patient's question:

21-year-old, there were thick blood roots at the base of the penis

Doctor's answer:

Considering it may be caused by the sebaceous glands of the penis, you don't need to worry too much. Currently, you can completely relax and take it easy. If there are no other discomforts in your body, there's no need to be anxious. It should have little impact. Pay attention to hygiene and regulate well in your daily life.
