My pinis skin is dark when flacid why is that..and is there something i can do to fix it?

Doesn't need fixin?: Penis skin, and skin on other parts of the genitals, is often a darker shade that the skin on the chest, tummy, thighs, and butt. It's just the way we humans are made. A penis can look darker when soft, because the skin is more wrinkled and won't reflect as much light. If the penis has a problem such as rash, pain, itching, or skin thickening, a primary doctor or a urologist can examine it.
