Dear Doc, I am 70 and uncut and tha past six months my foreskn on the inside gets very red and irritated after I have sex or even worse when I masturbate. Do you know of any thing that would help? -Mel

Dear Mel, To suddenly have a lesion inside the foreskin that is red and raw is potentially concerning. Unless it is a matter of drying out or trauma, I wonder about a precancerous or cancerous lesion or something like a herpes blister. The best way to explore this would be to refrain until healing occurs and see what happens. Is there any infection? Does it go away completely? If there is a persistent lesion you should see a physician. -Ellar, M.D.
