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 expressions include adult toy and the dated euphemism marital aid, although “marital aid” has a broader sense and is applied to drugs and herbs marketed to supposedly enhance or prolong sex. Sex toys are most commonly sold at a sex shop, but they may also be sold in a pharmacy/chemist store, a pornographic DVD store, a head shop, or a department store. Today’s sex toys are available in almost all countries for male and females.
