A penis sleeve (also called a "penis sheath" or "penis extender") is a sex toy that slides over the penis. It has several possible functions, depending on the design:

Functions of a penis sleeve:

Some sleeves are designed to make the penis longer and/or thicker during penetration, which can provide extra stimulation for some partners.

Many sleeves have a texture with ridges, nubs or vibrations , which can provide extra sensation for both the wearer and the receiver.

Some models function partly as a cock ring , helping to maintain an erection harder or longer.

A sleeve can sometimes be used when someone has difficulty getting or maintaining an erection, because the sleeve maintains the shape of the penis.

Important points to note:

Usually made of silicone, TPE, or rubber. Preferably choose a body-safe material such as medical-grade silicone.

Always recommended to avoid friction and discomfort.

Clean thoroughly after use with water and mild soap or a special toy cleaner.
Not all sleeves are suitable for safe sex (they usually do not offer protection against STDs or pregnancy).
