Pic didn't come through. These things happen. Have you recently used a different detergent, soap, condom, or lubricant? Fragrances in particular can be allergenic to many people. They can be quite irritating especially under a foreskin. Try soaking your unit in warm water with (unflavored) oatmeal in it twice daily for a few days. Apply a neutral non-fragranced skin cream, and maybe some triple antibiotic ointment mixed in.
