All Black silicone urethral sound, 8/10 mm

This flexible silicone urethral sound offers a gradual approach to urethral stimulation. Designed to progressively expand the range of your sensations, it combines a soft, body-safe material with a shape designed for gentle, controlled insertion.

Silicone material and care

I classify this product as standard-quality nonporous silicone—flexible, easy to clean, and durable over time. Silicone offers a smooth, pleasant-to-the-touch surface without the risks associated with porous materials (TPE, jelly). After each use, I recommend thoroughly cleaning it with lukewarm water and mild soap, followed by a complete rinse. You can also use a water-based sex toy cleaner—this is even preferable for removing residue.

Dimensions and progression

With its 24 cm total length and 8–10 mm diameter, this sound features a shape designed for beginners in urethral stimulation. The ridges along the shaft facilitate gradual insertion and allow for gentle sensory adaptation. This intermediate size is suitable for those who have already tried narrow sounds and want to progress gradually. I find that these dimensions offer a good balance between accessibility and sensation.

Safe use and precautions

Here is what you absolutely need to know before using a urethral sound. First, hygiene is critical—the urethra is a sensitive area that is easily prone to infection. Clean the sound before AND after every use. Second, water-based lubricant is mandatory—never use silicone lubricant or mineral oil on silicone (they degrade the material). Third, always go very slowly. Urethral sounds are not conventional penetration toys—every millimeter matters. In my opinion, a first session should not exceed 5–10 minutes. Finally, pay close attention to any signs of discomfort, light bleeding, or irritation—stop immediately and consult a healthcare professional if the pain persists.

Who it’s for and who it isn’t

Ideal for: Practitioners with prior urethral experience, people seeking gradual progression, and those who enjoy intense, controlled sensations. This sound requires patience and an understanding of your body.

Avoid if: You are new to urethral exploration (start with much narrower sounds), have a history of urinary tract infections, or are looking for a “plug and play” toy. I recommend consulting a healthcare professional before getting started, especially if this is your first experience.

Advice from a friend— Urethral sounds are not an impulse-driven activity. Take the time to learn, listen to your body, and make real progress. This is a practice that requires self-respect.
