Basic Technique ideas:

#1: Make sure she goes for a tinkle (urinates) just prior to this. The best way to “experiment ” is for the woman to relax over a bunch of pillows, face down, bum up in the air and legs comfortably wide apart. In that position with her guy either at the side, straddling one leg or sort of in the middle, the best way is with his thumb - inserted and pointing down towards the bed. If you press the thumb into the vagina until the heel of the thumb is pressing into her lips the GSpot will be right under the fat part at the end of your thumb. It’s no harder to find than that. It is a small bump roughly the same size as that fat part at the end of your thumb too so it feels a little like there’s another thumb pressing back. (ALL women have this - all women may not react the same way) Start to rub it. You can rub like you’re trying to get a spot out - back and forth or sideways or in a circular motion - it doesn’t matter. DO NOT do it too hard at first but once it puffs up and gets a little hard, that's when you can get rough with it. She'll feel like she has to go for a pee about then. Ignore her. Hold her down. Tell her to go ahead. Ladies you aren't going to pee. It just comes from some kind of build-up
and "about to release" feeling. Just hang on and tell him harder or faster to increase that feeling. The first time or two it takes a few minutes. Once you've done it a few times you can usually get the first orgasm in under two minutes - no matter what and then repeats every 30 seconds to a minute for as long as she can stand it.

#2 is: when you've triggered an orgasm, wait about 30 seconds, maybe a minute (no more)and then start again. Just as hard. Right away. It'll happen over and over as many times as you repeat it. DO NOT BE GENTLE !! Depending on what kind of shape she’s in, a slightly longer wait between orgasms is wise(ie. let her start to breathe again). My friends described those orgasms as like being hit by a train. It seems to involve the entire body. If they’ve never had a GSpot orgasm they are going to be amazed. When you do it to them again and again they will be astounded.

At that point an option that they all seem to enjoy is once she knows “that feel” she can climb on and ride you and position herself so that the end of your erection is hitting the same spot your thumb was hitting. She can then have a huge orgasm about every 10 to 20 downstrokes and keep that up until she melts or passes out. Then it’s time to cuddle.

One word of warning, guys, NEVER have her squat over your face, suck her clit and poke her GSPOT with your fingers. She will cum so hard and her pelvic thrusts will be so out of control that she will BREAK YOUR NOSE. Trust me on this. To combine the two (oral on the clit AND Gspot) she should be on her back and your face should be sideways to her.
