What little they have to say in their ancient texts on this topic (and many other topics) reflects their distate for the practices of all foreign peoples and cultures, as well as their
discomfort with all things pertaining to the erotic, such as
nudity, intimacy and bodily fluids — things that they themselves kept hidden and quiet about.
There's a potentially interesting discussion about the exploitation of the male form in Forgetting Sarah Marshall and how, in general, the reaction to male
nudity is a hell of a lot different than the reaction to female
nudity (there's a good reason that Colin Farrell's penis was excised from the already - unintentionally - funny A Home at the End of the World: male
nudity is a threat you respond to
with laughter; female
nudity is an invitation you respond to
with various levels of sexual
discomfort)-- but you can still have that discussion without actually enduring the picture.
