Hmmm... I'll definately have to give this a try. I wonder what it's actually pushing on though. If I recal my anatomy, the bladder is infront of the vagaina, and would be roughly in the area between the naval and the pubic bone. My girlfriend says that sex is generally better when her bladder is partly full, so it could be that putting pressure there stimulates another pleasure center or something. I know it works on men too, because my g/f uses some pressure there when she's on top. If I give her good feedback she can bring me to the brink and back about 10 times b4 I loose it, just by applying and removing pressure. Works great
, but only if your bladder half full or more.
