RJ put these scenes in for a different reason. It wasn't to show the reader how 'hot' a character was, but to show how awkward and strange it could be when two different cultures interact. Whether it was the borderlanders and community baths or Aiel with sweat tents or practically nude Seanchan dancers, the emphasis was on showing how strange other cultures may seem to us, and, of course, to put some humor into the series.
