Dilators

Urethral dilators provide a sensation that no other instrument can match: deep, internal, and directly on the most sensitive nerve tissue. Sounding—the use of dilators and sounds in the urethra—is one of the more niche forms of medical play, with a dedicated, passionate user base that finds the sensation irreplaceable.

What are dilators and sounds?

A dilator—also known as a sound, urethral dilator, penis dilator, or sounding stick—is a thin instrument inserted into the urethra through the opening of the urethra. In the medical world, dilators are used to treat urethral strictures. Within medical play and BDSM, they are used for the intense internal stimulation they can provide.

The sensation of a dilator differs greatly from other forms of stimulation: it is deep, full, and directly on the nerve-rich wall of the urethra. In men, this can also indirectly stimulate the prostate. In women, the urethra is located close to the clitoris and the G-spot, creating a unique sensation there as well. Urethral dilators, urethra dilators, and femdom dilators all refer to the same principle.

Types of dilators and sounds

Straight stainless steel sounds

Straight urethral sounds made of stainless steel are the classic choice. They are smooth, have enough weight to be easily inserted, and are simple to sterilize. They are available in increasing diameters, usually ranging from about 3 mm to 12 mm or more. Always start with the thinnest size. Stainless steel is body-safe and non-porous.

Van Buren dilators

Van Buren dilators are curved sounds with a characteristic S-shape that follows the natural curve of the male urethra toward the prostate. This allows them to reach areas that are difficult to access with a straight sound. Van Buren dilators are intended for advanced users and are not suitable as a first introduction to sounding.

Silicone sounds

Silicone sounds are more flexible than stainless steel and move more easily with the body. They feel softer during insertion, but are less suitable for deeper sounding, where the stiffness of stainless steel actually offers advantages. Body-safe silicone is non-porous and can be cleaned by boiling.

Sounding sets

A sounding set contains multiple sounds in increasing thicknesses. Ideal for those who want to gradually increase the diameter or experiment with different sizes. Preferably choose a set where all instruments are made of the same material for a consistent experience.

Safety with urethral dilators

Hygiene is essential for urethral use. Sterilize stainless steel sounds before each use by boiling them for at least ten minutes. Use only sterile lubricant; regular lubricants are not sterile enough for use in the urethra. Never use water as a lubricant.

Always start with the thinnest size and never force the instrument if you feel resistance. The urethra has a natural curvature and delicate mucous membranes that can easily be damaged. Use disposable gloves when handling the instruments. If pain persists when urinating after use, contact a doctor.

Frequently Asked Questions About Dilators and Sounds

What is sounding?

Sounding is the insertion of urethral dilators or sounds into the urethra as a form of sexual stimulation. The internal stimulation of the urethra provides a sensation that is unlike that of external toys.

Are urethral dilators safe?

When used correctly, with good hygiene, and sufficient knowledge, urethral dilators can be used safely. Sterilize the instruments before each use, use only sterile lubricant, and never force the instrument if you feel resistance. Beginners should always start with the smallest size.

What is a Van Buren dilator?

A Van Buren dilator is a curved, S-shaped urethral sound specifically designed to follow the natural curve of the male urethra toward the prostate. This model is intended for experienced users.

What lubricant should you use for sounding?

Use only sterile lubricant. Regular lubricants are not sterile enough for use in the urethra. Water is not a suitable alternative, as it does not provide sufficient lubrication and is not sterile.
