A stroker is a handheld male masturbator built for a repeating in-and-out motion. The category includes simple open tubes, textured sleeves in hard cases, and fancy shells with twisting caps. Grip on the outside matters when the inside is slick.

Open-ended strokers suit more anatomies and rinse in a single pass. Closed strokers add a suction trick if you cover the air hole. Texture maps are personal. What one review calls mild can feel like sandpaper on a frenulum.

Lube choice follows material. TPE wants water-based. Some hard-case internals are TPE even when the shell is ABS. Wash the part that touched skin, not only the pretty shell. Then dry the canal or you will invent a science experiment.

Grip and care

• A case with a slight taper is easier to hold than a wet sleeve alone.
• Flip or invert after use if the design allows.
• Do not store sealed and damp.
• Replace liners on a schedule if you use the toy often.
