Materials
- Jelly rubber ("jelly"). The most popular sex toy material that is convenient for designing any shape and texture of the shaft. It features a variety of colors, though jelly tends to suffer discoloration, and physical deterioration over time. This material contains chemicals called phthalates, which are thought to be harmful to gynecological and reproductive health. Unlike silicone (below) this material is porous, meaning that it can harbor bacteria.
- Silicone. Dildos and vibrators made of this material are durable and feature excellent non-porous properties, so they are easy to clean and maintain.
- Rubber. Many realistic dildos are made of rubber—a material that is both pliable and flexible enough for effective penetration. Like jelly, rubber is also porous.
- Glass. Glass double-ended dildos are usually created with special original designs. Glass is a smooth and firm material that delivers a cool feeling when used. It can also be used chilled and warmed for different feeling. Usually, glass dildos are made out of a special borosilicate type of glass, of which Pyrex, Schott-Duranglas and Simax are the most suited.
- Plastic. This non-porous and phthalate-free material is often used for creating double-ended dildos.
