ok well for as long as i can remember i have had many little bumps on the underside of my penis. ive never had sex and i dont think it is an STD. ive heard of other people that have them, but they don't know what it is. they are not big like herpes or warts. they are little round bumps, and every once and a while a white head will form. they do not itch, hurt, or irritate in any way, im just worried about what my partner will think. any suggestions on what it is? it is just tiny little bumps, usually same color as the skin.
