darker genitals

This is common in all races surprisingly. It happens more often in those with darker complexion tones, but it can happen to anyone. I noticed that when I was using Melanotan for a while that the skin tone on my genitals began to darken somewhat. I think that it is quite interesting and makes for an interesting contrast.
 
Usualy it is only the really pale/pasty people with "fair balls" (lol) ie: British people. Europeans with olive skin usualy have olive toned shafts and balls are either a darker tan color, or olive toned.
 
I'm of Chinese decent and my crotch is a bit darker than my body.

I prefer to think of it as friction burn... My boy bits have been well used.
 
I prefer the dark effect to the bleached shark-belly effect your feet get when you wear shoes and socks all the time. Can you imagine if your best parts were pale as fish meat?
 
I always thought I was strange in this. My dick is alot darker and I was engaged to someone who had trouble taking me orally and would always scrape (yeah ouch) and now I am very two toned. I hate it, I am tempted to sand paper my shaft to make it all the lighter, teeth scraped shade.
Anyone one know what to do to get a two toned into an even one toned dick?
 
good thread. I've always wanted to know who/why/how it becomes like that. the first time I saw one in-person I was kinda grossed out. no offense.
