What are the small white bumps under the glans?

Patient's question:

Detailed medical condition and consultation purpose: White small particles under the glans, moist, can be wiped off, itchy... No other discomfort for the time being
Duration of onset and persistence: Between 1 day and 1 week
Medical history: None

Doctor's answer:

The skin of the perineum is quite delicate, and the local environment is special, so local bacteria are prone to reproduce. Even if you pay attention to local hygiene, there may still be cleaning blind spots. Therefore, we need to clean with warm water daily, and if necessary, we can use low-concentration potassium permanganate for cleaning. If there is local itching without other obvious symptoms, you can apply some medication externally, such as Bactroban or erythromycin ointment. Alternatively, you can also apply moisturizing burn ointment or eczema cream, etc. All of these options are quite effective.
