A masturbation sleeve is a soft tunnel with a mouth, canal, and sometimes a closed end. The user adds lube and strokes. Internal textures do the variation that a dry hand cannot: spirals, nubs, chambers that pop over the glans.

Open ends fit more lengths and drain easier. Closed ends add suction if you cap the air hole with a finger. Materials run from easy-clean silicone to squishy TPE that feels more skin-like and asks for powder. A case that holds the sleeve in a rigid shell helps with grip when the outside is slick.

Wash as soon as you can stand up. Dried protein in a textured canal is a lost cause and a smell that never quite leaves. Invert if the design allows. A dedicated drying stick keeps the tunnel from staying clammy.

Lube and care

• Water-based lube for TPE unless the box says otherwise.
• A little lube goes further than a flooded canal.
• Keep powder off the inner texture; it belongs on the outer skin after drying.
• Replace when tears start at the orifice.
