In addition to the cylinder order size we need your cylinder length, standard lengths run from 8 inches and up. (Shorter lengths will be made upon request.) We suggest ordering a cylinder 2-3 inches longer than your erect length. For example, if you are 6 inches erect, an 8″ or 9″ cylinder length would work for you.
Two stage cylinders are sized by measuring with a string around the penis and balls (near where you would wear a penis restriction ring.) Use this measurement with the chart to determine the first stage size, the second stage should be 1″ – 1 1/2″ larger.
Plastic materials may vary in diameter up to one tenth of an inch. This does not affect fit of the cylinder.
