A penis sleeve, also known as a cock sleeve, is a type of penile support device that is worn over the penis during sex. It is designed to enhance the functionality of the penis and increase pleasure for both partners. Penis sleeves are available in a variety of sizes and designs and are typically made from silicone blends, rubber, or plastic. They can be used as sex toys, to mitigate erectile dysfunction (ED), or both. Some penis sleeves work by making penetrative sex easier for men with ED, while others increase the length and girth of the penis. Penis sleeves should fit snugly but comfortably over the penis when its erect, and its important to accurately measure your penis before purchasing one. To use a penis sleeve, it should be slowly inserted into your partner while ensuring the lube is evenly distributed and your partner is comfortable. When finished, the sleeve should be washed with a quality toy cleaner and stored in a dry, clean space.
