Dear Bearded Confidant,

Something strange I noticed for the past year.  I noticed this 'pimple' on my dick one day masturbating.  There was only one.  Eventually the whole thing falls off naturally without leaving a scar.  Then many months later I find another one. Same thing happens, it falls off and disappears.  What does this mean? What should I do?  Is this normal? 

Dear Acne_On_Penis,

Little bumps on the penis can be any number of things, from friction blisters to ingrown hairs to regular acne.  If you had said your pimples won't go away, I would have suggested having them checked out by a doctor.  But since your pimples are definitely temporary, I don't think there's any cause for alarm.  Try moisturizing your cock every night to see if dryness is contributing to the pimples.  Also, try using a different soap, in case any allergies are involved.
