A vibrator is a sex toy that operates by vibration and is often used to stimulate the human genitalia. The word "vibrator" is also commonly used to refer to other similar devices, such as massagers and dildos. Some vibrators run on batteries, but many others plug into an electrical outlet (wall outlet). Vibrators have been around for many years and were one of the first forms of massage therapy. Today, they're used in many different ways including sexual pleasure but also relaxation or relief from aches and pains caused by tension in muscles.A typical modern battery powered vibrator consists of a powerful electric motor with an armature that spins rapidly inside its housing when turned on. While most modern battery operated vibrators are controlled manually via buttons or dials on their surface, some models feature wireless remote controls that allow users to change settings without touching them directly.Waterproof vibrators are designed so they can be safely used anywhere you want: in the shower, bathtub or even hot tub! These personal massagers can be taken anywhere; whether you're traveling outside your home country or just trying something new at home--they'll always deliver pleasure no matter where life takes you!
