in smplified terms..
its like a tingling sensation that comes from the toes and slowly
moves all the way up close to your tummy....then the feeling comes
in waves and waves and waves while the gal tries to push it
down...
something like that...gals please correct me if i am wrong...
anyway.....some gals describe it to something like that numbing
feeling when your lef gets numb...not the needles type but more of
a spasm type...
