There is a second set of photos where he has the tape closer to the head, and it reads 5.5 inches too.
But on the other hand, he looks to have a couple of areas near the head in need of 1 or 2 ml of filler (he only had 8 ml).
I think from the photos that he still has a little swelling left and perhaps a reading 1 month out would show 0.4 inches (or 0.3 inches).
Also, while he reported that his
Erect penis length is 6.0 inches, that might be on a good day.
The reporting back of
Erect measurements is a little unreliable and perhaps measurements are requested too soon after the procedure.
