Urethral Sounds

The urethral sound is an advanced stimulation tool that is inserted into the urethra to explore unique sensations, often practiced as part of sounding or medical BDSM. Choosing the right diameter and material is essential for a comfortable and safe experience.

How does sounding work?

Sounding involves the progressive insertion of a rod into the urethra, a canal about 20 cm long in men, to stimulate the numerous nerve endings that line it. The urethral mucosa is particularly dense with sensory receptors, which explains the intensity of the sensations felt, including indirect stimulation of the prostate and glans from within.

Progression by diameter is fundamental: beginner practitioners generally start around 5 to 6 mm before considering wider models such as 8 or 9 mm dilators. A sterile water-based lubricant is essential for every insertion to protect the mucosa; check out our selection of suitable lubricants. Cleanliness of the equipment is non-negotiable: surgical stainless steel withstands sterilization, making it the reference material for this practice.

The different types of urethral sounds

• Straight stainless steel dilator: a classic and rigid model, easy to sterilize, ideal for beginners who want to control the insertion depth with precision.
• Electrostimulation urethral sound: integrates an electrical conductor connected to an electrostimulation box to produce pulses inside the canal itself, intensifying the stimulation significantly.
• Flexible rod: made of medical silicone or soft material, it adapts slightly to the anatomy and reduces discomfort during initial attempts, while remaining sterilizable.
• Urethral plug: shorter than a sound, it is positioned at the entrance of the meatus and maintains slight dilation, often used for prolonged wear in BDSM practices.

How to properly choose a urethral sound

• Diameter: always start with a thin model (5-6 mm) and increase gradually; never force a rod that is too wide.
• Material: favor surgical stainless steel or medical silicone, the only two sterilizable and non-porous materials compatible with high-end sex toys for men.
• Length: a 10 to 15 cm rod is suitable for most male anatomies; longer models are reserved for experienced practitioners.
• Function: choose a simple sound to start or an electrostimulation sound if you wish to combine dilation with electrical stimulation.
• Brand and certification: opt for specialized manufacturers like Metal Hard or ElectraStim, whose products comply with safety standards for materials in contact with mucous membranes.
