What is the best way to bandage your penis so the bandage doesn't fall off?

With tape, carefully: Keeping a dressing on the penis is difficult, and urologists have come up with a number of tricks to keep them on. The best way is to use waterproof (pink hospital plastic tape) or micropore tape to help support the bandage. Thin strips lengthwise along the penis can help. If hair gets in the way, you may need to clip it. Be careful not to fully encircle the penis, which could impact blood flow.
