Da Vinci's Demons - Twelve Inch Schlong

Have been watching season 1 of Da Vinci's Demons.
It can be found on Starz channels and some other non-premium cable channels.
More full frontal cock shots than I can recall ever seeing, even on cable.
Last night I watched episode 6.
There was a scene with several naked guys sitting around the bathing area I think,
and one stands (played by Vincent Riotta) up and walks past the camera,
swinging what looked to be a 12 incher.
Don't know if it was real, or a prosthetic added for effect.

Any other watchers see this and have an opinion?

Update:
