Take a good look at Hercules before getting started to acquaint yourself with your new pump, and read through the included instructions. The theory behind this great system is simple, once the penis is in place and comfortably surrounded by warm water, you'll push down on the cylinder to expel any excess, naturally creating a suction effect. Gentle yet definitely effective, the following pressure draws blood into the penis and surrounding tissue, creating a firm erection and in essence providing a workout for the male sex organ, keeping it in shape, so to speak, and operating at peak capacity. Even if you're a complete newbie, this pump is by no means intimidating, and use is virtually effortless.
Once in the tub or shower, you'll fill the inner cylinder with water and insert the relaxed penis inside. There's a slanted side to the gaiter's sealing ring, this should be placed against the testicle area to avoid unwanted pressure in that area. When the base is evenly placed around the base of the penis, push down on the cylinder to release excess water. You may need to repeat this step a few times, optimal suction occurs when no more water is expelled. At this point, you can lean back and relax, letting the suction do its work. If at any point you experience discomfort or pain, you can immediately eliminate pressure by pushing the quick release valve at the top point of the Hercules.
