Thank you for your insight.
Hi
Bumps on the penis are common and most do not have a serious cause. Even then it is better to seek prompt medical advice.
They can be due to several causes like: Papules (as seen in molluscum contagiosum, hair follicle infection, pearly penile papules, fordyce spots, psoriasis and warts); Ulcers (seen in primary syphilis, chancroid, granuloma inguinale, lymphogranuloma venereum, penile cancer, herpes simplex, etc); and plaques (seen in balanitis, lichen sclerosis, psoriasis).
It seems from your description that you might be having Fordyce's spots. These are small, painless, raised, pale or white bumps 1 to 3 mm in diameter that may appear on the glans, shaft or scrotum. They are harmless and appear in most adults, so there is no reason to panic. They may occur as a solitary lesion, but frequently appear in crops of 50 to 100. They generally cause embarrassment and sometimes fear that they might be sexually transmitted. They are actually abnormally dilated blood vessels, covered by thickened skin and may bleed if injured or even during intercourse. Generally no treatment is advised but laser or electro-dessication methods are sometimes employed.
You should consult a doctor for a proper diagnosis and treatment.
Take care
