How do you cure brush burn on a penis?

To treat brush burn on the penis, first gently cleanse the area with mild soap and water to prevent infection. Apply a soothing ointment, such as aloe vera or a petroleum jelly, to keep the skin moisturized and promote healing. Avoid any irritants, such as tight clothing or friction, until the area has healed. If pain or irritation persists, consult a healthcare professional for further advice.
