You need a fair size cock and you dont have to hit the G spot to give her an orgasm

As far as I know girls have two. One being the clitoris...which is located outside the vagina. Another is on the inside. It's just past the cervix, which is why women usually like men with long penises because it's easier to the this particularly nice spot. Hope that helps.

stick two fingers in and pull up and toward you really fast.

There are medical diagrams all over the net that you can use to locate the G-spot.

I think your single mindedness might negate the whole process though. A woman's body is covered in erogenous zones and you should think of an orgasm as an accumulation of pleasant sensations, not as a single event that starts and stops in seconds. Remember women do not operate physically or emotionally in the same way as men. Just banging away at her G spot might not be enough.

At least you're making an effort though :)

multiple orgasms are teh bestest!

u have to stick your c*ck at least 2 inches into her...then push it up twords her stoumack and there is a squishy thing. thats the G-spot and then just mess around with it.

move your dick to the left if that doesnt work play with her clit she will cum in seconds if she tells you she doesnt like when you do that shes lying OH..... DONT FORGET TO CUT YOUR NAILS FIRST JUST A LITTLE ADVICE

ignore these idiots.the g-spot is inside the vagina and to the front.use your finger next time you have a willing partner and feel the rough area that will be in the front wall of her vagina if she is laying on her back.this is some debate if the gspot is a special place or just another area inside the vagina.

Yep.
