The controls are usually located on the bottom side of your vibrator

The vibration is controlled by a switch on the bottom of the g spot vibrator's base.This can be either a button or dial, depending on the model. The intensity of the vibration is controlled by this switch, and it will either have multiple speeds or just one speed setting (depending on your toy).The controls are usually located on the bottom side of your vibrator, but they're sometimes located at an angle so you can adjust them easily while using it.
