Yes, all women can squirt. It's done by stimulating the G-spot until it swells and fills with liquid. The reason why most women don't squirt easily is because just before the body naturally releases it's fluids, you experience a feeling that is often compared to an urge to urinate. Most women fear that and repress it, causing squirting to be much more difficult than it would otherwise be. If you want to learn to squirt, I would suggest trying it alone first and becoming comfortable with it before sharing your newfound ability with a partner.
