I saw a comment about the guys on Monsters of cock. The old guys like Castro & Ramone had INSANE girth with very,very nice length with it. But now they have a lot of VERY lengthy black guys with less girth.
Not saying those guys are not big by any means. BUT BangBros have enough knowledge to know things that make a guy look bigger. Camera tricks, Interracial(Contrast makes them appear bigger), TINY/Skinny/short chicks,etc.
