Hi, Welcome To HCM & Thanks For Asking Your Query Here If you ve never had sex, little bumps on the shaft of the penis may be pimples, a skin cyst, or ingrown hairs. These are common and they re nothing to worry about. Another condition that s normal and no cause for concern is pearly penile papules. These whitish bumps appear on the glans (head) of the penis or along the edge of the glans in many guys. Pimples, cysts, ingrown hairs and papules won t do any harm — though if you try to pop them they could get infected. but if u r sexually active and had multiple sex partner than bumps on the penis may be signs of sexually transmitted diseases (STD). Painful blisters, bumps, or ulcers may be herpes. Genital warts (HPV) also can show up as bumps on the penis. Sometimes these are irregular in shape or hard to see, and they re not painful. Syphilis also can give a guy painless ulcers on his penis If you re concerned about bumps on your penis, see a doctor or go to a clinic for advice on what to do. Don t try to pop any bumps or use pimple cream on them, as this could make things worse. I hope it help Thanks & Get well Soon
