G spot orgasm could be existed in a woman in less then 10 minutes fingering if the partner do the right thing and have the skill to locate the spot. It is appox. 1-2 inches on top (11-1 o clock)of the vagina, it"s sizes like a 50 cents coin and a little bit pop up in an irregular surface, so it's easy for one to feel it's position. The major point to stimulating G spot is not necessary touching but up pressing, with correct strength of up pressing, some could cum in less then 5 minutes if the woman used to obtain G spot orgasm. This is my experience.
