G-spot is the area a few inches up the front wall of the vagina, where the vaginal wall enters in contact with the arch of the clitoris – the internal area where the two bulbs join. The more the clitoris gets aroused and swollen, the more it becomes sensitive to the pressure.
Tip #1: start by stimulating external part of clitoris by applying the rounded head on the hood to build up excitement, with gentle speeds.
Tip #2: move the vibrator internally with the rounded head towards the front wall of the vagina to stimulate the G-spot. Increase the speed and start playing with the pulsation modes.
