don't forget though, that no matter how much you stimulate a clitoris, much of what goes on is in your head, ie even after 30 minutes of stimulation you also have to appreciate the guy or woman you're with to really enjoy the act other wise you might as well use a piece of liver or just do it yourself, which is why if a woman can't get off on her own it's doubtful some guy can get her to orgasm.
