A sex toy is an object or device that is primarily used to facilitate human sexual pleasure, such as a dildo or vibrator. Many popular sex toys are designed to resemble human genitals, and may be vibrating or non-vibrating. The term sex toy can also include BDSM apparatus and sex furniture such as slings; however, it is not applied to items such as birth control, pornography, or condoms. Alternative terms for sex toy include adult toy and the dated euphemism marital aid. Marital aid also has a broader meaning and is applied to drugs and herbs marketed to enhance or prolong sex.
A dildo is a sex toy, often explicitly phallic in appearance, intended for sexual penetration or other sexual activity during masturbation or with sex partners.

A dildo's circumference is typically 4–5 inches (10–13 cm).
