For quite a while I've had small bumps in a band on the shaft of my penis near the glans. they're not closely clustered like hpv, and only slightly raised, about 1mm if that. I had health services at my school check it out and they told me it's not hpv, but probably just the texture of my penis. However, with friction the area can become dry. There's no irritation or itch, just bumps. Anybody have any Ideas?
