Understanding lumps on your penis

What causes penis lumps?

Lumps of penis refer to small or, sometimes large, swellings or growths on the surface of the penis. The causes or types of the lumps can be divided into the following two categories:

Normal cause of penis lumps

You should always keep in mind that penile skin is often bumpy and lumpy, so it's possible that you're simply mistaking that as a lump. The bumps on your penis could also be sebaceous cysts of hair follicles or an allergic reaction, both of which are harmless and non-contagious (you won’t transmit those while having sex). Or, alternatively, the raised surfaces could be pearly penile papules, which often appear as one or two rings of small "pearly" or domelike bumps that form around the glans (the head) of the penis and are also nothing to worry about.

Abnormal causes of penis lumps

However, it's quite possible that the bumps are indicative of a more serious STD, such as HPV (human papillomavirus), which can cause genital warts that are either raised or flat, white or flesh-colored, and usually don't itch or burn. Less common is MCV (molluscum contagiosum virus), which is related to the pox family of viruses and appears as clustered, whitish bumps with a central indentation. Both conditions often require removal by a topical treatment or surgical procedure. Herpes may also show up as bumps, bite-like pimples or a crusty rash with no physical discomfort, though it more often manifests as sores or blisters that do itch and burn.

All three of the above STDs are viruses, so they can be spread through skin-to-skin contact with the infected area; even when symptoms aren't present. And, since it's impossible to determine what the bumps are without a medical diagnosis, you should encourage yourself get checked out by a doctor while the bumps are still visible, i.e., as early as possible. Until then, your best bet is to play it safe and avoid contact with your partner's genitals (even with a condom) until you get a clean bill of health.
