I think the type of crying ShaniFaye was talking about is kinda like a build up of nervous tension and sometimes when women orgasm, it acts as a trigger to release that tension in a overwhelming flood of emotion. The emotion can be released as tears, laughter and even muscle spasms...
At least this was the explanation a girl gave to me, on why she was rolling around the bed in a fit of hysterics (just after her orgasm)... Either that or my tiny cock was tickling her tuppence!
