The Cock Grip Double allows you to have your penis and scrotum individually under control. If you're one of the men who would like to increase their stability, but have gained no experience with the right tools, the Cock Grip Double is the right entry-level model for you. Slip the top loop over your penis and draw the string until you reach the desired level of tightness. The second loop goes around your scrotum, and follows the same process, giving you a completely customizable experience.
