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.
