It's important to assess any new or changing moles on the skin, especially in sensitive areas like the genitals. While many moles can be benign and genetic, there are certain characteristics that may warrant further evaluation by a healthcare professional:

Asymmetry: If one half of the mole does not match the other in shape or color.
Border: If the edges are irregular, ragged, or blurred.
Color: If the mole has multiple colors or has changed in color.
Diameter: If the mole is larger than 6mm (about the size of a pencil eraser) or has grown in size.
Evolution: Any change in size, shape, color, or symptoms such as itching or bleeding.

Since you mentioned the mole is medium-sized, flat, and has been present for several years without symptoms like pain or bleeding, it may be benign. However, given its location and your history of phimosis, it would be wise to consult a dermatologist or urologist for a thorough examination. They can assess the mole more accurately and determine if any further action is needed. Early evaluation is key to managing any potential risks effectively.
