actaully i first thought of spreadsheet as a means of calculating money and investments, but was a bit embarassed to say it, lol! but the "spread the sheets" thing is good too. of course then there's "spread cheeks/spread sheets" - hey! you asked!
on a very basic level it could just mean you are trying to assess your sexual currency or attractiveness. in this society that is a big deal. i guess its good to know just how attractive the opposite sex finds you. perhaps for a woman this might be a more important issue, as this culture (rightly or wrongly) places a high value on sexually attractive women. and lets face it, a very sexually attractive woman has a big advantage in many ways in modern day america, and definitley when it comes to money.
anyway, figuring out your sexual identity and your relationship to your own sexual nature is a good thing, and dreams provide a way to do that in a very uninhibited manner (not that you sound very inhibited!)
