No. The insertable part is obviously bigger than the penis in case of Barrett Long.\
The dildo says the insertable length is 8.5. Kind of how whole dildo is 10 inches but the insertable length is 7.5. So 7.5 inches is Shanes actual length wouldn't that make Barrett Long penis size 8.5 like his dildo's insertable length?
It's pretty much impossible for the dildo to be smaller than the penis (that's why Shane isn't bigger than his dildo). But it definitely is possible and most of the time a fact that the dildo is bigger than the penis.
If we are generous and don't count in the suction cup, Barrett still is only 7.2" in this picture.
