Note i'm not an average person.
So you may not wish to add this to statistical record.
I was a petite, soft voiced, blonde girly bloke, yet I was -abnormally- huge, like two arms at the time... later on as the testosterone hit me I actually started shrinking into nothing, losing my libido too. Still up in the top echelon of girth though. I think it's how I reacted to hormone changes, and the lack of female company.
My voice is soft, light and dreamy but still somewhat impaired. My body has a heroic 6' skeleton, but only a bit of fat and very little meat.
I have an extremely wide vocal performing range, including many forms of beatboxing and whistling. The only thing I can't seem to replicate again is an ultra-high-pitched scream. I needed training to reach the baritones and lower, and I do enjoy the deep sounds when composing music.
Recent measurements would be tight XL when flaccid, and a vice-like fit when erect (still not exceeding length). I can comfortably touch my index and thumb around it when it's thinner, otherwise not even the middle finger reaches (only the vein can be squashed).
An angular tapering head, foreskin that cannot stretch even halfway down it, perfectly straight and held at a high angle, and a curvaceous wavy sides. The only thing marring it is the recent construction of supply lines.
