I guess nudity is shown for two reason to entice carnal desires and to show the private side of the characters.
Taking a crap would also show the private side of thongd so why isn't it shown?
In all honesty I find both disgusisting but nudity less.

They're trying to build a certain character. Thinking about the character taking a dump isn't something the writers want to use to construct the audiences perception of their personality. Of course in occasional movies the lead roles are meant to be see as dumb, awkward and lacking control.
Lots of characters aren created to be sexy, confident and in control with sex. There are people that still see sex on tv as vulgar and there were people that didn't see it that way initially as well.
