Penis sheaths

Cock tubes are rigid sleeves that are placed over the penis—for a different kind of pressure, for BDSM play, or as a creative sex toy. Here you’ll find cock tubes made of plastic, metal, and silicone. Check out the full selection of all cock & ball toys or go back to all sex toys for men.

What is a penis sheath?

A penis sheath — also known as a cock tube — is a rigid or semi-rigid sleeve that is placed over the penis. Unlike a soft penis sleeve that conforms to the body, a penis sheath is made of hard material and provides a tight, restrictive sensation. Penis sleeves are used in BDSM contexts for control and restraint, as a playful erotic accessory, and in some models as a reduction or enlargement aid. Penis sleeve and penis tube are the primary search terms; “penis tube in English” is a common search query for the English name—which is cock tube or penis cage.

Types of Penis Sheaths

Cock Tube as a BDSM Accessory

Rigid tubes made of plastic or metal that completely encase the penis. In BDSM use, the sheath provides a sense of restriction and control. Similar to chastity cages but less focused on long-term wear and more on active use during scenes. See also our selection of chastity and chastity cages.

Decorative Cock Tube

Cases made of colored plastic or metal with a playful or visually striking appearance. Used as an erotic accessory during roleplay or for visual stimulation of a partner.

Penis tube for reduction

Tight tubes that compress the penis — for the sensation of restriction or as part of a size kink. Specifically focused on the visual and tactile effect of a tight enclosure.

Penis sleeve versus penis sheath

A penis sleeve is made of soft, stretchy material and increases the effective girth of the penis for the partner. A penis sheath is made of hard material and provides a restrictive, tight sensation — not intended for penetration but for the sensation of the sheath itself. Always use lubricant when applying tight penis sheaths to minimize friction on the skin.

Frequently Asked Questions About Penis Sleeves

What is the difference between a penis sleeve and a chastity cage?

A chastity cage is designed for long-term wear and features a lock or closure system that allows a partner to maintain control. A penis sleeve is typically designed for shorter, more active use without a locking mechanism. Both provide a sensation of restriction, but their purpose and duration of wear differ. Check out our selection of chastity and chastity cages for chastity cages.

Are penis tubes available in all sizes?

Penis tubes are available in various inner diameters. Check the inner diameter carefully before purchasing—a tube that’s too tight causes painful constriction, while one that’s too loose has no effect. If in doubt, choose an adjustable model or one with a slightly larger size.

How do I clean a penile sheath?

Clean hard plastic and metal penile sheaths with warm water and mild soap. Metal models can also be disinfected with 70% isopropyl alcohol. Check whether the model is waterproof before submerging it completely. Allow it to dry completely before storing.
