My 7-year-old uncircumsized son gets small red blisters around the tip of his penis after swimming. He says they are very painful. If we put vaseline on it before swimming, it doesn t happen, our thinking with this was that the vaseline would repel the water. Could this be from the chlorine in the folds of his skin.
