What is a fleshlight?

A Fleshlight is a masturbation sleeve designed to simulate the feel of sexual intercourse. It's typically made from a non-porous material, often a type of thermoplastic elastomer, and features an internal textured structure designed to provide stimulation. These textures vary widely in design, offering different sensations. The sleeves are generally cylindrical and come in a variety of sizes. They're designed to be cleaned and reused, and are considered a relatively discreet and private option for sexual self-gratification. Many different brands and variations exist on the market.
