Men's electro sex toys have come a long way in the last 10 years and thanks to modern technology, we're able to create groundbreaking new toys that push the erotic boundaries of e-stim even further. The ElectraStim Jack Socket E-Stim Stroker is a double award-winning compact realistic stroker. It has a curvaceous internal texture, skin-like movement and a lifelike feel, but the similarities with other men's sex toys ends there... With a squeezable outer case applying adjustable pressure and bipolar 2mm connection for an estim stimulator, the realistic sleeve comes to life; making your shaft throb and pulsate with pleasure. Relax and tighten your grip to enhance sensation and use plenty of water-based lube to intensify your pleasure with every stroke. In order to accommodate all penis sizes, Jack Socket is available in one of two sizes- Standard or XL. Although the size difference between the two may seem subtle, the extra space within the sleeve of the XL allows for a more comfortable experience for men with a penis girth to 1.9inches (diameter). The two sleeves also offer different textures specially designed and tested to provide the optimum stimulation. Standard has a raised bumps texture that squeezes you tightly for intense contact while the XL sleeve has an indented ‘ribs' texture that produces a subtle suction sensation during use. A tube of conductive gel is also included. Both sleeves fit inside the same black silicone outer casing. Sleeves are also available separately if you wish to purchase a replacement.
