What problems do penises have?

Patient's question:

Age
Detailed medical condition and purpose of consultation: When the penis is not erect, the foreskin covers most of the glans. Is this considered phimosis?
There is white discharge in the groove of the glans. When the penis is not erect, it is only 5 cm long, and when erect, it is only 13 cm long. Is the penis too short?
Additionally, at this age, most men's penises are dark, but mine still looks like a child's.
Duration of the current illness and persistence: Since childhood until now
I feel embarrassed to tell my family, so I have never gone for a check-up!

Doctor's answer:

In your case, it's just that the foreskin is a bit long, not considered overly long, so it's considered normal. For people like you, where the foreskin can be easily retracted with a gentle pull, or the glans naturally exposes itself during an erection, no treatment is needed, and surgery is not required.
It's well-known that phimosis and balanitis can cause significant harm to patients, so it's important to seek treatment as soon as possible. In daily life, pay attention to dietary issues and avoid spicy foods. Maintain a balanced diet. Additionally, regular follow-up visits can be scheduled if necessary.
