A growing online trend that sees people using electricity for sexual pleasure is drawing fresh warnings from experts, despite claims from enthusiasts that it can produce far more intense orgasms than traditional masturbation.
Known as e-stim, short for electrostimulation, the practice involves applying low-voltage electrical currents to intimate areas of the body. Supporters say the technique can increase sensitivity, boost pleasure and even lead to hands-free orgasms.
Interest in e-stim appears to be growing online, with Reddit communities dedicated to the practice attracting thousands of members. Users regularly exchange advice, discuss equipment and share experiences, with some claiming the sensations are so powerful that conventional masturbation feels less satisfying afterward.
Also known as electrosex, e-stim involves the use of electrical currents applied directly to the penis and testicles for sexual pleasure.
According to sexologist Becky Crepsley-Fox, the concept is far from new. Speaking to Metro, she explained that electric play dates back to the 1800s and has evolved through various devices over the years, including the violet wand and TENS machines, which were originally developed to help relieve muscle pain.
Modern e-stim setups often include a shaft ring connected to a stimulator that allows users to control the strength of the electrical pulses. Adhesive pads can also be placed on the testicles, while insertable devices are available for anal and vaginal use.
Crepsley-Fox explained that the sensations are linked to increased sensitivity and blood flow.
"For people with penises, increased engorgement can create a sensation of greater firmness," she told Metro.
"The testicles are particularly responsive, the skin is thin, nerve endings are densely packed, and many people find even low-level current there produces an intense sensation."

While some users praise e-stim for its effects, experts warn that the practice carries significant risks.
"Placing pads too high on the body can cause cardiac disruption," Crepsley-Fox warned.
She advised that people with heart conditions, epilepsy or pacemakers should avoid e-stim entirely. The article also notes guidance from the CDC and American Heart Association recommending that users maintain at least a six-inch distance between devices and electronics and avoid high-voltage equipment.
External electrical currents near the head or neck can also trigger seizures.
Other reported risks include muscle spasms, nerve damage and electrical burns. Some users on e-stim forums have also reported experiencing genital numbness lasting up to 24 hours after a session, particularly when using high power settings rather than increasing intensity gradually.
Another concern raised by users is desensitisation. Some participants in online communities say they found traditional masturbation less satisfying after regularly using e-stim.
"The normal way used to be get in the mood... and the finish would be great," one Reddit user wrote. "Now, when I do it the normal way on my own it just feels a bit underwhelming."
Sexologists say this can happen because the body adapts to the type of stimulation it experiences most often, although they note that normal sensation can return after taking a break from e-stim.
For those who choose to experiment with e-stim, Crepsley-Fox recommends starting at the lowest setting and increasing intensity gradually.
She also advises using only purpose-built equipment, avoiding homemade devices and keeping electrical stimulation below the waist and away from the heart.
The sexologist further recommends trying e-stim with a partner present, particularly for first-time users, in case a medical emergency occurs.
