That would have to be one of the largest and longest camelstoes I have ever seen. One could fit a horse in that thing...
I looked up some facts and wondered if you would reconsider your statement :-D
Veterinary and animal reproduction literature reports measurements for stallion penis (erect) girth/circumference, though values vary by breed and study. Typical reported erect circumference (girth) for adult stallions is roughly 25–40 cm (10–16 in), with larger draft breeds toward the upper end and smaller breeds/ponies toward the lower end.
