The G spot has to he vigorously touched by the **** (I started a thread on this that my current bf cannot last longer than 5 min to do this) Its different for every woman I think...it takes alot of patience and practice...

It's true! Multiple orgasms do not have to occur as far apart as hours from each other. Some can occur as little as 10 seconds apart. The so called G-Spot, named after the OB-GYN whom discovered it; is the same as the male prostate gland. These organs are both responsible for releaseing fluids out of both the penis and the vaginal track. The G-Spot is in fact one of the most sensitive areas in the woman for sexual stimulation.
The only way possible for the G-Spot to be fully stimulated is by the proper insertion of a penis. Next time you are with your partner, notice how the penis has a tilt to it, it almost looks curved. This bannana shape allows the penis to stimulate the entire G-Spot area. It is more a zone rather than a spot. The entire surface area that makes up the G-Spot is roughly around 2 squared inches.
The positions updraft discussed are very successful ways to maximize stimulation of the G-Spot. Don't forget, the G-Spot is located 2.5-3 inches deep and on the top side on the vaginal tract. Not even "fingering" or manual stimulation can compare to what sex does for this area. By lifting your legs, or basicly "shifting your pelvis"; you lower the position of your G-Spot and elevate the position of the penis. You should try to adoid arching your back, unless you think that the penis is well curved to still stimulate this area.
If this is all done correctly, a women may expiriance her first of many orgasms in as little as 4-5 minutes. Each orgasm that follows may be as little as 30 seconds to 2 minutes apart. You need not stop sex during these intervals. Sex may last as long as you can physically endure, as long as your partner can last, or as long as the kids don't wake up. Don't forget to consider, that the longer you have sex in this fashion, the more orgasms you will have, and each one will be more intense than the previous one.
