Honestly, I tend to think that the BBC is probably a porn manufactured fantasy. Porn lies to us as it is. since most of us rarely see other men with erections in real life, we rely on porn which is skewed towards the larger side. With "bigger is better" being the prevailing message on the internet, I wouldn't be surprised if average/small guys were less likely to post pics of themselves. I can't imagine what it's like for black guys with average and small penises living in a world that expects them all to be 8" x 6".
