to cum back to the question: when i first saw black guys on white chicks porn on the web i was quite young. all the porn i have seen before was kind of real people body type vanilla stuff similar to what is sometimes mistakenly called porn for women, so it was quite different to what i knew before.
so at first i was a little bit shocked, but also turned on. it was not because of race but the male performers had the hugest cocks i have ever seen at that time. and they seemed so adequate for the female performers.
that was when i became curious about cock size, never really having seen another mans erect penis in real life let alone a black mans (there werent any black people around at that time). i also wondered if there were any differences between races.
then when i started watching more and diverse porn i learned that size is just a key value in the porn industry, i also recognized that there were just as many hung white performers as are blacks. but obviously that does not show the real proportions as jobs in the porn business are defined by the market not percentage in human society.
sometimes i read statements on forums that form to an image of an average size and how this value spreads. when i began dating girls they never complained about the size of my member, sometimes they even made compliments about it.
now it is not of a big deal to me any more. i am confident with what i have, knowing i am considered slightly above average. but i also know the pleasure a girl can feel only with a really big one (no matter the race).
but when i am asked to help women get a date i always take them to locations where we can find lots of black people, knowing the slightly better chance to get a real big one. most black people here come from the west central africas, and i hear a lot from women who have had the experience.
one particular girl that is well known and said to be a slut (not literally, but she is just what we call an "easy girl") who has had lots of experiences with both white and black guys told me that not every black guy is really huge, but of all black guys she dated the smallest was what is just average for the white guys around here, but she never had a really small one. on the other hand about half of her white lovers have been rather small and hardly any was real big.
She said if she is to propose a guy to one of her friends it will always be a black one. and eventually she somewhat convinced me. i mean why look for a needle in a haystack? and not directly go for a well-endowed black guy? this is what i often suggest to my female friends. and most of the times it works out right and proves the fact!
