A dildo generally is an object with a phallic shape that is used for vaginal and anal penetration. The shape can be anatomically inspired by a penis, however fantasy shapes and shapes that help stimulate specific areas of the vagina or anus are also popular.

The material varies a lot as some people like softer textures and other people like harder textures. Very common materials are silicone and rubber however metal, hardened glass, and other materials are also used.

In cheap dildos a jelly-like material containing phthalates is used to achieve the texture. These are however not always the safest option due to them being porous and not able to be cleaned properly. These are sometimes still used by adding a condom over them.

Some dildos have extra features like a built in vibrator or a tube that allows for artificial cum to be injected through the dildo into a person.

Dildos can be used by one's self, but also with a partner. In some cases it is also used as part of a fucking machine or strap on as the part that is inserted. Larger dildos can be used for stretching and therefore there is such a huge range in dildo sizes to be found.
