>>101450864I recall a chemistry teacher (who graduated medschool IIRC) who explained that dark hair and darker skin comes with some pheromonal byproducts that make you want to fuck.
Bottomline, according to him, every dude is wired to want to fuck melanin endowed black haired women.
The problem with that is that even though your dick wants it on some level you still can't deal with the bone structure and other characteristics usually associated with these chicks.
/co/ /a/ and /v/ chicks fix that by being the color that makes you want to seed her innards while retaining desirable white features (mostly more delicate facial features and hair that doesn't look like you could scrub dishes with it).
They are fictional and therefore can be engineered to have the best traits from each ethnic group.
You can search for real versions of these chicks in Desi chicks, latinas and others... but your chances will be waaaay better if you there's at least some european blood in the genepool.
I particularly like Rozena Ally and Nicole Bexley. Also, brownbunnies usually has some darker skinned chicks without strong african facial features.
