Uncut, you just hit on one of MY secret lusts. The gay redheaded redhead male! They are like type AB- blood; they are out there, but very, very rare.
I'm not going into Scruffy's speculations on evolution. Who knows? And I'm not a dermatologist, but I have picked up this little tidbit in my time. We are taught that skin color depends on the presence of the pigment melanin. More melanin, darker skin. That's pretty simple. In reality, there are (at least) 2 different types of melanin, a lighter one and a very dark brown/black pigment. Most of us have a combo of the two types, resulting in different shades of caucasian, oriental, or negro skin. Caucasian redheads, however, are mutants who lack the dark brown pigment, and have only the lighter brown coloring, and then in varying amounts in varying places. I've seen brown haired guys with carrot red-yellow pubic hair, and I'm sure most of us have. Funny, I don't think I've ever seen true red pubic hair as you see on some guys/girls heads. Also, the mutation originated in Northern Scandinavia. Where ever the Vikings traveled, and they traveled and enjoyed the sights alot, they gave rise to redheads. Seen mostly in Northern Europe, lots in Ireland and Scotland, along the Danube, into Hungary. (A red headed Hungarian in a bath house, hmmm)
Be that as it may, the lack of the really dark pigment results in those pretty creamy pink penises and scrotums.
