First off, forget what you saw in porns. Just take all that info and toss it out the window.
Second, many women squirt when their g-spot is being stimulated, though some do when their clitoris is. It may take more stimulation than you think. Try straight pressure. If that doesn't work, try rubbing. Or tapping. Or pulsing. Or any combination of the above. A dildo with a g-spot curve is very helpful.
Also, this may sound weird, but some women squirt without even knowing it and it may or may not come with orgasm. It's not always obvious. Some squirt. Some gush. Some dribble. But if you are looking for something like you saw in porn with the epic amounts of fluid, you are likely to be disappointed.
