How can I make sure my girlfriend is satisfied in bed?

I would like to know what I should do so that when I'm fingering my girlfriend she has plenty of orgasms.

when you stick your fingers in use your middle finger and your ring finger. stay towards the top and you'll find a something like a ball of skin. push on this when you finger her, it really gets my girlfriend going

Hey db4mu, thats called the cervix and um, no that is not what gets your girlfriend going. There is a soft fleshy spot in the front of a womans vagina known as the G-spot. That and the clitoris is what gets us going. You don't need to use 2 fingers, you just need to know how to use 1 correctly. Btw, if you push on it or get to rough with it, you could cause an infection or damage it.
