I mean, dude has a point, and not just on his penis.
Most guys don’t see a wide range of dicks. The ones they usually see are selected to look good on film or at a distance, which means much bigger than average.
If you ever work a job that’s dick heavy, you start to figure out that porn dicks are rare. And that they’re often not as big as they’re made to look via camera and positioning tricks. Then again, you also end up seeing the outliers more often, which can be entertaining.
Steve-o is a tad on the large side of the usual range, based on the images and footage (or inchage, I guess) I’ve seen.
