it could be the lotion. even though it's meant to moisturize an inexpensive lotion can contain alcohol and other drying chemicals and some of these substances can cause dermatitis or allergic reactions. keep in mind too that a lotion is actually meant to be absorbed so it doesn't really do the trick as a lube. you're better off using a water-based personal lubricant meant for the purpose and you can follow up when you're done by washing and then applying a penis health creme (health professionals recommend man1 man oil) to soothe moisturize and rejuvenate the skin.
