Little pimples under foreskin

Answer 1

These are called penile pauples or penis pimples and there are different kinds.

Pimples on a penis or the testicles typically occur in teenage years, but it is also possible men will experience pimples at some time later in their life. Statistics claim that eight out of ten men will experience pimples on penis and/ or testicles at some time in their life. Most of the time penis and testicle pimples go away as person grows, or if they occur later in life, they subside in a matter of week or two. But the fact is that if they don't, it is not wise to sit at home miserable, hoping they will go away. If you notice any new lumps or bumps, ask your doctor to check, or go to a genitourinary medicine clinic. I know it can be suffering, not to mention the psychological effect pimples on genitals can cause.

Normal Kinds:

So called (and looking like) pimples are normal. They are pearly penile papules, small in size (approximately 1-2 mm) and they look just like pimples, but are not pimples. They are actually tinny glands, and you shouldn't pick on them. They occur around the margin of the penis head, and can be seen when foreskin is pulled back. They usually develop in teenage years, but may occur up to the age of 40. They are visible in some men, while in others are less noticeable. Around 10% of men is affected by pearly penile papules.

After masturbation or sexual intercourse hard swelling might appear near the foreskin, in the shaft of the head of the penis. This swelling is called lymphocele, and is caused by temporary blockage of the lymphatic channels at the area described. This condition is also normal and goes away on its own without any after-effects.

Papules are small lumps (less than than 1 cm), raised above the skin surface. Most penile papules do not have a serious cause (pearly penile papules for example), but some are infectious and may lead to more serious conditions.

Types of papules:

Molluscum contagiosum is form of papules, which is very common, but must be supervised by doctor. They are pinkish-white round lumps, each about 1-5 mm in diameter, and are caused by a virus.

Hair follicles are a normal and are usually found on the underside of penile shaft. They may be visible or only felt as small lumps in the skin. They are recognized by having a hair arising from them.Pearly penile papules (described above as very normal condition)

Fordyce spots are small (1-5mm) bright red or purple papules that can appear on the penis or testicles. They usually affect younger men, and appear in crops. They are painless and not itchy, but are embarrassing because of their appearance.

Not Normal:

Crust, or ooze of any kind. This is most like a papule, and you should just talk to your doctor about it. Its all very common.
