My girl wants to experience a gspot orgasm

make sure your fingernails are clipped & smooth & use them to go to town;

basically your first 2 fingers inserted (relaxed) into her vagina will naturally curve in - the g-spot is "around about" where the tips of your fingers will be (although that depends on the length of your fingers & the size of your girl). it feels kind of ridged, especially when she gets excited & the tissues start to engorge.

take everything slow & when you eventually get to the g-spot gently caress/massage it; you should (both) get some good results then.

so - at least, that's my technique, and it seems effective ;)

do a google image search on 'g-spot location' & you'll get a bunch of diagrams.

have fun

Let me give you a couple of suggestions on this one.
First, there are a variety of different toys on the market today that are meant just for this goal. They are curved in just a way that is perfect for reaching that hard to reach spot. I am sure you will find it fun to experiment with.

Second, and my personal preferred method, is fingers. Trust me on this. It is much more intimate. Get down there with your fingers and slide a couple of those babies inside your girl and gently work them around, and in and out. Explore her. Her noises will let you know when you are doing something really write. And the whole experience will make you hotter than you will believe. Something about having your woman get herself off on your hand is incredible. Once you do it once, you will be anxious to do it again. And so will she.

Don't forget the most important rule though.trim those fingernails first.scratching the outside skin is sexy.the inside skin is painful.
