E-Stim is the abbreviation for electrostimulation (also known as electrosex) and describes a sexual practice that uses DC or low-frequency alternating currents for sexual stimulation. These are usually used for E-Stim developed devices - but it is also suitable TENS devices for E-Stim .. These are much cheaper than commercially available E-Stim devices. You can try it on your hand, arm or leg to see how you enjoy the sensation. You should know what to expect before bringing it into bed. This might seem obvious, but do NOT make your own e-stim toys
