A type of sex toy. The user inserts his penis into the toy to enjoy pleasurable sensations.

Male masturbators often use materials that mimic the feel and texture of the vagina, anus, or mouth, allowing for more realistic sex. As male masturbation toys are not self-lubricating, a personal lubricant can greatly enhance the experience.

Depending on the material used to create the masturbator, users may be able to choose from water, silicone, or hybrid water-silicone lubes (oil-based lubes will often break down the soft materials used to make these toys). Many high-end male masturbators use Cyberskin, a material made from silicone, and they may break down and become tacky when used with a pure silicone lubricant.
