I wrote a whole thing about it a few times and I'm not going to again. Search on the internet there is a lot of info. You have to know were everything is on her first and not rely on the tool. You need to know were to use the tool(vibrator).. Her G spot is a patch of sponge like tissue inside and up, find it. Her Skene's gland can be stimulated with insertion and again up it's underneath her bladder. It also can be stimulated by pushing gently on her lower abdomen or above her pubic mound with penetration. Make sure she's hydrated and if she feels like she has to pee tell her to let it out. It can be urine or she can ejaculate. Keep on trying and learn female anatomy, modern anatomy. Look up Skene's gland. Many articles confuse the G spot and Skene's gland, they are wrong, they are confused. They are different. http://en.wikipedia.org/wiki/Skene's_gland http://www.newscientist.com/article/dn2495-bigger-is-better-when-it-comes-to-the-g-spot.html http://www.newscientist.com/article/dn2495-bigger-is-better-when-it-comes-to-the-g-spot.html http://everything2.com/index.pl?node_id=1545039 http://www.incontinet.com/skenesgland.htm http://en.wikipedia.org/wiki/Female_ejaculation Keep searching on your own and keep at it.
