LOL Mrs Jones...but you're right.... melanin stops at certain parts of the body, and that applies for everyone regardless of race or coloring.
Genitalia-wise, all women have pink parts.
And dont bring up penises (not unless you're going to use that thing!) because the shaft is covered with the same sort of skin as the rest of the body, just thinner.
Sex ed, I teaches it. *G*
Interesting article in Wiki about why there is a tendency for men to prefer lighter skinned women regardless of race, and for women to prefer men with darker skin.
Sexual preference for paleness in women by men has been found in cultures throughout the world. The effect has been discovered in Moorish Spain, where the ruling class was of darker complexion than the conquered natives. [ 10 ] In recent years, several research projects have suggested a general preference for lighter-skinned women by African-American men. [ 11 ] In his foreword to Peter Frost's 2005 Fair Women, Dark Men, U. of Washington sociologist Pierre L. van den Berghe summarizes:
- "Although virtually all cultures express a marked preference for fair female skin, even those with little or no exposure to European imperialism, and even those whose members are heavily pigmented, the trend ... in integrated societies has [been toward] increasing popularity for men of colour, especially those [of] African descent. These trends have been recorded in areas such as South America, where in Brazil it was estimated that by 2009 black people of African descent will be the single most dominant ethnic group. In popular media in the western world 'blacks' have been repeatedly surrounded by advantageous stereotypes and myths that praise their athletic aptitudes amongst many other things, and often depict them as males of superior genetic inheritance."
However, there is an abundance of negative stereotypes as well. In Western societies, persons with dark coloring, particularly those of African origin, were viewed negatively for centuries. Such stereotypes almost always worked to the advantage of the dominant (white) culture. While there is evidence that these prejudices are fading, the wide level of variance between positive and negative stereotypes for the same skin tone indicates both the power and the arbitrariness of such issues.
The reason behind that may be something innate, like preferring women with a .7 hip to waist ratio, regardless of weight. Some evolutionary behaviorists believe it may be that the human brain associates something with lighter and darker skin and gender as being advantageous.
That thing may be that lighter skinned women have less trouble assimilating certain vitamins that are necessary for a healthy baby during pregnancy. That may be the reason that as people went north out of the equatorial zones, lighter skinned humans gained a few advantages, like more easily assimilating Vitamin D, where in those sunnier zones, it wasn't much of a survival advantage.
Of course, we have better diets and supplements that make that a non factor now, but it may be why men in all culures are almost universally attracted to lighter skinned women, and women to darker skinned men, relatively speaking. Evolution is weird and doesn't care about racial issues, it just heightens traits in humans that give you the best chance of getting more humans into the gene pool.
The opposite phenomenon, men of darker skin being preferred by women, has a basis in adaptation too. Darker skin is a physical advantage for men who work outdoors in physically demanding jobs. That very often goes along with upper body strength and women are universally attracted to signals for upper body strength, the "T" shaped torso in men. I call it carrot shaped guys, but just like men are biologically wired to look for .7 hip to waist ratio, women are biologically wired to look for darker skin (than their own), broad shoulders and chest, narrower waist and hips in men.
YMMV, because there are of course, other cultural and social influences,as the article points out that can and do override this, but on a purely biological/genetic level, this is what humans tend to think is "sexy".
