Hi FO, others
With all due respect, scientific inquiry doesn't work that way (no evidence either way therefore I'm right). The burden of support is on the other side especially if the argument is that all woman can squirt and it's just a matter of the wrong stimulation when they can't. Certainly, there are credible cases, a lot in fact, of this (though in some cases researchers argue that there are different forms of squirting and what some people think is g-spot related squirting isn't and could represent a potentially harmful urinal condition). And, as I noted, some women just are not wired (nerved) that way is what studies are suggesting.
WHile I don;t have time at the moment to link a bunch of studies, try the following to start. I really really hate to use Wikipedia but this is a good quick start as the article on this is fairly well done and there are linked studies. It frames and clarifies many of the points I've made in my posts on this and should help.

While I do respect your opinion (honestly) from a researcher's view its untenable. There is just a very very big difference between all and a few. I think such a view falls into the performance issue stress traps Dan and Jen discuss in one of their videos. At best , the evidence is questionable so probably the best summary is some woman can squirt but exactly why and what it is varies and is debatable but as of yet there is no evidence that with the right stimulation any woman can squirt. That is just a serious reach.
The video link (and info above) by FO is fine on technique but please don;t presume if this doesn't work for you, something is wrong with you or how its being done.
