when my clit is rubbed in a certain way/spot my legs shake uncontrollably, its really funny, there must be nerves connected from my leg through that area, because I can't help it its really odd. And I can't do it myself, only guys can do it, its really random. but when its happened they don''t seem to mind. its either sexy or amusing. for me its a mixture, it feels great but I find it really funny!
