I think this new cup technology for briefs from Aussie Bum
will only work if you have sizable balls to 'cup'. While I love to check hot guys' bulges, it's the erect cock size which matters, not the appearance of the package.
Some packages can be deceiving which is why on other than black guys, I do a dick size check. This usually means grinding on it or stroking to see if it passes the cut-off point. As with fishing, I throw the little ones back!
