My problem with their statement is that it's so ... definitive. They're not really leaving any room for this works for some people, but it doesn't for others. I know too many people who can only come from clitoral stimulation or by solo-masturbation only to believe any one things works for any one person.

Your situation is extremely interesting to me, because it's a change from something that used to work and now is painful. I wonder if it's the changes in your body more than emotional/mental changes? Now *that's* a scientific study in the making!
