Does the G-Spot exist?

The Twin Research and Genetic Epidemiology Unit led by Andrea Burri and Professor Tim Spector has published a study claiming that there is no evidence that the G-Spot or Gräfenberg Spot exists and it is simply a myth.

The survey asked a mere 1804 female twins aged between 22 and 83 a number of questions about sexuality, including does the G-Spot exist?

56 percent claimed to have a G-Spot however their identical twin did not always agree suggesting it is a myth.

Andrea Burri who led the research said she was anxious to remove the feelings of inadequacy among some women who fear they do not have a G-Spot.
It was also suggested that some men are also under similar pressure to stimulate the G-Spot.

It sounds like Andrea Burri presumably lacks the G-Spot and we would therefore like to invite her for a practical awareness consultation.
I had previously assumed along with many others that its something you either have or don’t have, or is that a female orgasm?
Surly all those G-Spot stimulation toy manufactures are not pulling your leg are they?

Apparently this survey was the largest of its kind so we would like to conduct our own research and ask you to decide.
