From what I see you're missing an important option- the combo of g spot and clitoral stimulation. I need hard, fast thrusts with a very curved toy to squirt but I also need clitoral stimulation, often less than if I was getting off clitorally alone (which never makes me squirt) but without something on my clot, its not going to happen. My wife can occasionally get off on G spot penetration alone but she says its a lot better if she gets clitoral stimulation too. From what I've read, that's often the case with many women, g spot alone just won't quite too it and it takes a combination. And stimulating multiple parts of the body at once tends to make for a more intense orgasm whether you're squirting or not.
