For those that are into numbers: (these are all inches)

Beau from Beau (II)

Bicep 24.25
Forearm 18.78
Wrist 10.31
Chest 55.34
Waist 40.45
Thigh 30.32
Calves 23.91
Ankle 12.33

And believe it or not, he is actually quite the shortie!

Height: 5'4"

And of course, genitals:

Penis length: 19.5 inches
Penis girth: 16.45 inches
Scrotum length: 9.86 inches
Scrotum girth: 24.25 inches

EDIT: Forgot to mention this is flaccid, as he most certainly is not erect in Beau II.

Just to give you some perspective, a grapefruit or a softball is about 12 inches in circumference. So Beau's big bull balls are literally each the size of a grapefruit.

Alas, there is no way to "weigh" him so I haven't the foggiest idea what a guy his size and height should weigh. :(

The current Beau (from Beau III) is quite a bit bigger than this, but I've yet to measure him.

I got these measurements using the excellent Measurement Metrics for DAZ Studio plugin.
