If a man had a flat mole on the shaft of his penis and stretched it out, would the mole fade in color or stay the same? asking because i have a black spot on mine that fades when that happens?

You are spreading the pigmentation causing the color to fade. Good Luck

With stretching the same amount of pigment is spread over a larger area it would appear less intense in color. For healthy diet: http://www.choosemyplate.gov/., exercise 30 minutes/day, drink enough water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs. Get HPV and Covid vaccines. Wish you good health!
