Measuring 5.1 inches in length, it’s an ideal beginner’s urethral dilator and comes in 5mm, 7mm and 9mm diameters to suit different levels of expertise.

Use some lubricant along the length and gently slip the urethral sound into your penis. Once in place you can power up your ElectraStim stimulator to experience intense throbbing and heightended sexual arousal that can be enough to bring you to a powerful orgasm hands free.

It works well just like it's advertised to do

The 9mm is too big for me at this time. I will try a thinner sound.

Great experience.

Great product, well engineered and good instructions for a novice.

Electro Urethral Sound (Multiple Sizes)

I've used all the sizes, from 5mm to 9mm. Each has their merits. I've found they work best with the metal scrotal loop, although I've not tried an anal probe, which may be better. The 5mm goes in real easy, and has an intense stimulation , especially when it's slowly drawn towards the penis tip. The 9mm is awesome when first used. It really fills the urethra and is indescribable. It has to be drawn up slowly, and the sensation is deeper. The 7mm is somewhere between the two. They can bring you close to orgasm but I've not kept one in during that. Well worth trying.

Very stimulating

Was a concerned about the size of this toy, but on arrival found that it fit quite nice. Certainly learned about keeping it in all the way however. The charge will catch you by surprise when it starts coming out of you.
