Answer

The G-spot is hard to find if you search for it from cold. Try looking for it on the front (inner) wall of the vagina when you are already highly aroused, preferably after a clitoral O. When you touch it you will almost certainly feel a sensation of excitement. You may also release a clear fluid, even ejaculate, so it's a good idea to have a couple of good, thick towels ready. Some women claim that G-spot stimulation is ideal for multiple Os. Good luck! Some women even have an 'out-of-body experience' ('floating') from the Os.
Once you've found the G-spot you might explore the area just behind it. This was first named in 2002 at a conference in Malaysia and the gynaecologist would presented the paper named it the A-spot in honour of Asia. (The name has nothing whatsoever to do with 'atomic'). Many women find that when they are highly aroused the A-spot can produced even more powerful and thrilling Os than the G-spot ... SO, enjoy.  

Answer

There is actually no scientific evidence that the elusive G-Spot even exists. Studies have been done to look for increased nerve endings or other changes that would indicate hwere of if this is a reality. However, there does appear to be an area just behind the pubic bone on the front wall of the vagina that does produce and prolong orgasm when stimuulated. So if it feels good, do it, and have fun looking for the elusive G-Spot.  

Further answer

The G-spot is a name widely given to the urethral sponge, which **does** exist and contains Skene's glands, which are almost certainly responsible for female ejaculation.
The term 'spot' is misleading. It's an area, not a magic button or automatic route to ecstasy. The area is only exciting for a woman when she is already highed roused.
The Wikipedia article on the urethral sponge (see link below) states: "The urethral sponge encompasses a large number of nerve endings ..."
See links below.

Actually, many women I've been with claim that the stimulation of the urethral sponge "feels weird" or irritating. Though a few found it quite exciting. It seems to be based on personal preference. Oh, and the best way I've found to locate the "g-spot" is to use your finger like a hook and apply pressure on what would be the back side of the clitoral tissue. On the anterior(front) vaginal wall. This is from a male perspective so you might need to experiment a little with the angle of attack. The tissue is usually dense so a far amount of pressure is required. And as others have said, it tends to be more stimulating while already highly aroused. In my personal(non-scientific) opinion, the "g-spot" is merely an internal extension of the clitoral erogenous zone because certain women don't seem to enjoy it as much as others. Sometimes it is even uncomfortable or irritating. So see what works for you and enjoy.
