Safety & Sizing

Your pump tube should be large enough to allow the tissue of your penis to expand, but not so large that it begins to pull your scrotum into the tube when pumping. Mr. S recommends a tube that leaves roughly a pinky’s width of gap between the outside of your erect penis and the inside wall of the tube.

To find the right size, wrap a string loosely around your cock when hard and measure the string's length. Then use the following guide to help determine the cylinder size you need.
