Electric "Catheters" are unipolar products which must be used with another toy which is in contact with the body. "Catheter" is probably not an accurate term for these products, as they are only meant to be inserted a minimal distance into the urethra and never beyond the shaft of the penis. This product is made of a solid, flexible conductive silver/silicon material. These conductive catheters produce a totally unique sensation (especially when used with a butt plug or insertable electrode). It's not uncommon to produce ejaculation without any manual manipulation.

Electric "Catheters" are available in 3 sizes:
