There are tiny black bumps along the shaft of my penis along with what seems to be regular penis acne. Should I be concerned?
If you are dark skinned or have very curly dark hair, the most likely cause are hairs pushing up through the skin, especially if the spots are mostly near the base of the penis. These would be concerned normal and not harmful.
If you are dark skinned and the spots appear to have a textured top, these can be genital warts. Genital warts are spread through oral sex or sexual intercourse. These need to be removed since they can lead to cancer later in life. You would need to see your doctor about this.
Most likely it is just hairs pushing up through your skin.
