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 ment to be inserted a minimal distance into the urtheria and never byond the shaft of the penis . This product is made of a solid, flexable
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:
Small: 1/8" diameter X 6" long
Medium: 3/16" diameter X 6" long
Large: 1/4" diameter X 8" long
Note: Always use plenty of water based lubrication with this toy. Also note that lubricants containing nonoxynol-9 can be very irritating to the urethra and should be
avoided with this application.
