there's a how to vid floating around somewhere... i might have watched it in POW... the dude who made the vid guarantees it worx haha. looks a little rough though. at times it looked like he was carrying a bowling ball or a 6 pack.
EVERY woman has the physical ability to squirt. Not all of them do it because of psychological/social barriers and/or they don't know about it. In these days, IMO, a girl who has trained herself to squirt like a fire hose is a sex goddess. Look at Cytherea and Angela Stone.
