Stays on & stays slippery in water.
Shower Jerk is a water-activated personal lubricant.
It has been designed solely for use in water & wet environments.
Other lubricants, including other silicones, wash off or quickly degrade in water. Shower Jerk does the opposite; it gets more slippery as you add more water.
Stop using soap. Graduate to a product designed to enhance your pleasure in the shower, bath or hot tub.
