In this case you are the flat earther. Flat earther have also their 'researchers'The same way you know the earth is not flat, plenty of medical researches around the g-spot

General skepticism
In addition to general skepticism among gynecologists, sexologists and other researchers that the G-spot exists,[3][4][5][6] a team at King's College London in late 2009 suggested that its existence is subjective. They acquired the largest sample size of women to date – 1,800 – who are pairs of twins, and found that the twins did not report a similar G-spot in their questionnaires. The research, headed by Tim Spector, documents a 15-year study of the twins, identical and non-identical. According to the researchers, if one identical twin reported having a G-spot, it was more likely that the other would too, but this pattern did not materialize.[4][9] Study co-author Andrea Burri believes: "It is rather irresponsible to claim the existence of an entity that has never been proven and pressurise women and men too."[40] She stated that one of the reasons for the research was to remove feelings of "inadequacy or underachievement" for women who feared they lacked a G-spot.[41] Researcher Beverly Whipple dismissed the findings, commenting that twins have different sexual partners and techniques, and that the study did not properly account for lesbian or bisexual women.[42]
Petra Boynton, a British scientist who has written extensively on the G-spot debate, is also concerned about the promotion of the G-spot leading women to feel "dysfunctional" if they do not experience it. "We're all different. Some women will have a certain area within the vagina which will be very sensitive, and some won't — but they won't necessarily be in the area called the G spot," she stated. "If a woman spends all her time worrying about whether she is normal, or has a G spot or not, she will focus on just one area, and ignore everything else. It's telling people that there is a single, best way to have sex, which isn't the right thing to do."[43]
Nerve endings
G-spot proponents are criticized for giving too much credence to anecdotal evidence, and for questionable investigative methods; for instance, the studies which have yielded positive evidence for a precisely located G-spot involve small participant samples.[3][5] While the existence of a greater concentration of nerve endings at the lower third (near the entrance) of the vagina is commonly cited,[1][4][8][44] some scientific examinations of vaginal wall innervation have shown no single area with a greater density of nerve endings.[4][5]
