On a more serious note, apart from being a lovely colour ...
They seem to have fewer inhibitions sexually ... I don't mean that they are up for doing anything ... but that a lot of folk are brought up to think even vanilla sex is somehow sinful ... most black women I have seen regard shagging as something as natural as eating or breathing.
They laugh easily and look lovely when they smile, the contrast between white teeth and brown skin is marked.
Pale skin shows up every blotch and blemish which is often not the case with darker skin.
I fancied the pants off a black school girl when I was a school boy, short skirt, white knee length socks, brown thighs exposed between sock and skirt, white blouse, coffee coloured smiling face, button nose, shortish Afro hair, drove me mad .... the lust has stayed with me ever since.
