We've all heard of the G-spot, but there's still some scientific uncertainty around the topic: some studies claim it doesn't exist, while others says it definitely does.
According to this video from BuzzFeed, a gynaecologist called Dr Gräfenberg spoke about a very responsive zone in the walls of the vagina back in the 1950s. It was later named the Gräfenberg spot, aka the G-spot.
Scientists are unable to determine the exact location of the G-spot within the vagina, but they believe that the location may be different for different people.
To stimulate the G-spot, it's been suggested to insert a finger (or two) upwards into the vagina and curve the finger in a "come here" motion.
It is also thought that doggy style is the best position for stimulation.
