Hi and welcome to HCM.
Pearly penile papules (PPPs) are tiny lumps seen in neat rows around the corona of the glans penis
. They can occur as a single row, or in multiple orderly rings encircling the corona. PPPs are numerous, uniform, symmetrical and dome shaped, and vary from 1 to 3 mm in length. PPPs occur in up to 20% of men.
You may be having Fordyce spots
which are visible sebaceous glands and occur along the shaft of the penis they often appear in adolescence. Fordyce spots are more easily visible when the skin is stretched, and many patients may describe them as a lump that appears during an erection. They are a normal anatomical variant that does not require any treatment.
If they are bleeding and causing you pain and discomfort, then please contact a local doctor.
