Charlie Hunnam

So Charlie Hunnam was erect at the urinal? You can't determine someone's actual true penis size while they are peeing haha.
Correct, my fellow penis scientist. However, my powers of deduction tell me that if it already looked impressively large when it was soft, it could only be equally or more impressive when hard. Because a penis can stay the same size when it hardens, or it can grow bigger, but what it does not do is shrink when it gets hard.
Thanks for coming to my TED Talk.
