The urethra is surrounded by the urethral sponge (also known as the G-spot), which is made of spongy erectile tissue that contains paraurethral glands and ducts. You can feel the G-spot through the front wall of the vagina, about 1 to 2 inches (2.5 to 5 cm) inside the vaginal opening.
Like the clitoris, the G-spot is not just an isolated spot of sensitivity, but part of a network of nerves, muscles, and tissue. When a woman is turned on, the glands within the urethral sponge fill with fluid, causing the sponge to swell; as it becomes more pronounced, it’s easier to find and more sensitive to stimulation. The more turned on a woman is, the easier it will be to find her G-spot. So, before you go hunting for it and especially before you start stimulating it, make sure you warm her up.
When you start to find the G-spot, make sure your fingernails are clean and short, before you begin. If not you may consider slip on a latex or nonlatex glove to transform your fingers into exciting tools.

Slide a finger inside 1 to 1 .5 inches and aim to locate the G-spot. Compared to another place inside of the vagina, the G-spot will have a different texture. It will feel wrinkled or ridged.
Be sure to warm her up with your fingers before using a toy.
At this time, you may lube up the G-spot vibrator and slide it inside her 1 or 1.5 inches to reach the G-spot. And aim for the curved head of the vibrator at her G-spot. Only a little bit of movement the vibration
does most of the stimulation.
