How to measure your penis correctly...
To get the most out of your Hydromax.
Measure the length of your penis
Measure your erect penis with a ruler pressed lightly onto your pubic bone. You`ll find a ruler is easier than a tape measure.
Record the measurement from the pubic bone right up to the tip of your penis.
MEASURE THE GIRTH (CIRCUMFERENCE) OF YOUR PENIS
Measure the circumference of your erect penis around the middle of your shaft
You’ll find a tailors tape measure is easiest, but a piece of string wrapped round and then measured against a ruler after will do.
