Hitting the g-spot

I want to try fingering my girl friend some time soon and I want to make it as pleasurable as possible for her. I've heard that I can massage her G-spot while licking her clit and that will drive her absolutely nuts with pleasure.

How do I find the g spot, apparently it's about 2 inches into the vagina and on the upper wall. Will it be obvious when I hit it, like does it feel different or will she immediately react?

Also about how long will it take for her to have an explosive orgasm after I start? 5 minutes, 10 minutes? longer?

Thanks

what handkerchief?

You have incorrectly used an apostophe.  The word geeks is a mere plural.  You're welcome.

Your tone is rather rude.  Keep it in your pants, cowboy.

Way to bump a five year old thread, dude.
