Clitoris: Usually obviously visible right above the vaginal opening, like a little pink button. It’s the most sensitive part outside the vagina and is often a good place to start when initiating sees after foreplay. Gently stimulating it can help the vagina lubricate (get “wet”) and tent (lengthen to its aroused state to accommodate penetration). It’s also the part to focus on during cunnilingus (eating pussy).

G-spot: About an inch or two into the vagina on the anterior (front or upper) wall on the same side as the clitoris. Feel around with your finger until you feel a spot that’s more porous (“spongy”) than the rest. Stimulating this spot is the easiest way to cause female ejaculation or squirting. It’s the part that the thickest part of the base of the penis stimulates during traditional PIV sex.

A-spot: Lesser known than the first two. It’s the deepest point in the anterior fornix, which is the pocket in front of the cervix, or on top of it if the vagina-owner is lying on their back. During front-entry PIV sex, it’s the spot that the tip of the penis hits. Unlike the clitoris and G-spot, it needs a little more pressure to properly stimulate, so the ideal way to do it is with a phallic object concentrating the force into the tip. Just be careful not to hit the cervix as that can cause discomfort or pain.

P-spot: The deepest point of the posterior fornix. Same rules as the A-spot, except that it’s behind the cervix, or below it if the person is lying on their back. It’s hit by the tip of the penis during rear-entry PIV sex.
