What are penis plugs and cum stoppers?

A penis plug — also known as a penis stick, penis sticker, or cock stick — is a thin rod or plug that is inserted into the urethra of the penis. The urethra contains a high concentration of nerve endings that, through internal stimulation, provide an intense, unique sensation that cannot be achieved through external stimulation. A cum stopper — also known as a cum plug, sperm stopper, or cock stopper — is a variant with a stop mechanism that delays or blocks ejaculation. Penis plugs, hollow penis plugs, and metal penis plugs are all search terms for variants of this type of product. Urethral play and sounding are the English terms for this type of use.

Types of penis plugs and cum stoppers

Solid penis plug

A solid rod made of stainless steel or silicone that is inserted fully into the urethra. Penis stick, penis rod, and dick plug are names for this type. The material is smooth for minimal friction during insertion. Metal penis plug and metal penis sticks are the most popular versions.

Hollow penis plug

A tubular plug with an open channel running through the center. Hollow penis plug and hollow penis plug are specific search terms. The hollow design allows for urination while the plug is worn and also enables ejaculation. Popular for long-term wear.

Sperm stopper / cum stopper

A penis plug with a stop mechanism—usually a ring or seal that prevents ejaculation. Sperm stopper, cum stopper, cum plug, sperm stopper, and sperm stopper are variations of the same search term. Preventing ejaculation creates an intense, pent-up sensation. Cum stopper, cock stopper, and penis stopper refer to the same type.

Penis plug set

Sets of multiple penis plugs in increasing diameters — ideal for discovering which size is comfortable for you before investing in individual models. Always start with the thinnest one in the set.

Safe use of penis plugs

Penis plugs require strict hygiene—the urethra is a direct pathway to the bladder. Use only products specifically designed for urethral play. Sterilize metal plugs before each use by boiling or disinfecting with 70% isopropyl alcohol. Use special sterile, water-based urethral lubricant—not regular lubricants. Always start with the thinnest size and never force it. Stop immediately if you experience pain, a burning sensation, or bleeding, and consult a doctor if symptoms persist. Never use products made of unknown materials or without a smooth finish. You can read more background information in 11 tips for urethral toys.

Frequently asked questions about penis plugs

What is the difference between a penis plug and a cum stopper?

A penis plug is a rod or plug intended for stimulation of the urethra. A cum stopper has the same insertion part but adds a stop mechanism that delays or prevents ejaculation. Some models combine both functions. Cum stopper and sperm stopper are the most commonly used names for the stopper variant.

What material should a penis plug be made of?

Only body-safe, smooth materials: 316L stainless steel or medical-grade silicone. Steel is easier to sterilize and smoother than silicone. Never use plastic, rubber, or materials not specified for use in the urethra—the mucous membranes in the urethra are extremely sensitive to irritation from porous or rough materials.

How do I clean and sterilize a penis plug?

Stainless steel plugs: Boil in water for 5 minutes or disinfect with 70% isopropyl alcohol, then rinse with sterile water. Silicone plugs: Boil. Always clean before and after use. Store in a clean, sealed container.
