Hanes2008 has a measured girth pic that does look only semi hard like he says. It's 19 cm or 7.5 inches without being fully erect. When he's fully erect, it does look thicker in my opinion, so I would say his 8 inch girth in all probability IS real!
Oh, and NO apparent edema of his penis skin -- which is simply swelling of the skin with excess fluid -- that you see on guys that pump and claim a huge girth because of the temporary dermal edema. This guy does not pump to temporarily increase his girth either.
