This may be off-topic, but I hope you won’t mind:
According to engineering, the structural stability of a hollow cylinder increases when the length (height) vs. circumference ratio decreases. Researchers tested this on a group of ED patients, correlating the severity of their condition with the length/girth ratio of their penises. The correlation showed without doubt that those with girthier penises were in clear advantage. As the length/girth ratio increased, the blood pressure in the CC had to be significantly higher to maintain erection. The study demonstrated that often the “pencil penis” condition was the main cause of the ED.
I don’t recall the link right now, but I could find it if anyone is interested…
