A dildo is a sex toy designed primarily for penetration and sexual stimulation. It is often used as an alternative to an actual penis or as part of partnered play. The word covers many shapes and functions: some are simple, non‑moving objects while others include mechanical features; some are chiefly aesthetic, others are tailored for specific anatomy or sensations. Dildos are commonly discussed within broader resources about sex toys and sexual health (sexual wellness).

Common characteristics and materials

Dildos vary by shape, size, texture and material. Design differences affect feel, flexibility, and intended use. Important features to consider include whether the toy is rigid or flexible, whether it has a flared base for safe anal use, and whether it is compatible with harnesses or suction mounts.

  • Plastic — often rigid and inexpensive; see plastic options for firmness and finish.
  • Rubber and jelly — softer and flexible but can be porous; information about rubber materials highlights cleaning and safety concerns.
  • Metal — non‑porous, heavy and temperature‑responsive; many users like metal for firmness and ease of sterilization.
  • Wood — finished and sealed wood pieces are artisanal and durable; guidance on wood construction advises on proper sealing and care.

Types and design variations

There are realistic dildos that mimic anatomical detail, abstract shapes aimed at targeted stimulation (for example curved tips for G‑spot or prostate), double‑ended models for shared use, and short plugs intended for anal play. Some dildos integrate vibration or pivoting mechanisms, blurring the line between a dildo and a vibrator; others are strictly non‑vibrating.

History and cultural context

Phallic objects used for erotic or ritual purposes appear in the archaeological record of several ancient cultures, and references to artificial sexual aids exist in historical texts. Modern manufacture expanded with new materials and changing social attitudes toward sexuality in the 20th and 21st centuries, increasing availability and diversity of designs.

Uses, safety and care

Dildos are used for solo masturbation, partnered sex, gender-affirming practices, and therapeutic purposes like recovering sexual function or exploring anatomy. Safety guidance includes choosing non‑porous, body‑safe materials (medical‑grade silicone, glass, stainless steel), avoiding sharing without a barrier such as a condom, and cleaning according to material—soap and warm water for most; boiling or thorough sterilization only where material permits. Avoid products with known harmful additives (for example certain phthalates), and inspect toys regularly for damage.
