Not everyone's a David, and if you're lucky enough to measure up as more of a Goliath we've got a water wonder just for you. The Goliath Bath Mate penis pump is known as the world's largest penis enhancer, and measures around 2 inches longer and 30% bigger than the Hercules. It's also wider to accommodate girth. Used in the bath or shower, you'll be that little bit larger before you can say lather up'. The Goliath is built for penises up to 10.24 inches long and 2.56 inches in circumference, and promises to make you even bigger and longer. The benefits are immediate, as this beauty increases bloodflow and gives your penis a hearty health check. It doesn't just increase the length of your penis, it enhances your erection too. This multitalented pump also helps to combat erectile dysfunction, and the use of water promises even distribution for maximum results. If the thanks we get for turning you on to this handy enhancer is as big as the results you'll get, we expect a stadium-style standing ovation.
