is gender important (slightly off topic)

Im sorry to ask what must appear to some a stupid question;
have you ever pretended to be a member of the opposite sex, either to shock, annoy, fool or defraud?
the reason i ask, recently been in conversation with a 'lady', wanting to get messy with messyamature and me.
i may act the fool, but im not, so was suprised and disappointed that this lady, may not be all she seem, or more than....
honesty is a wonderful trait.
more to the point, knowing how dirty messyamature is, she wouldnt mind one way or the other lol.
again, sorry if its a daft question, but is it commonplace?
