Displays of Affection

There has long been controversy over whether or not Indian lovers kissed.  Of course, no one can forget Kevin Costner (Lt. Dunbar) and his beautiful Indian woman, Stands With a Fist, and their toe-tingling liplocks in Dances with Wolves.  Did the writer take creative license and expand the romance for the sake of making the movie more appealing?  I know, as a romance author, I've had some pretty passionate scenes in my books, but I can't find much written about the "custom."  I recently sent off an email to an American Indian forum and I'm waiting for a response, but what I discovered in by book, The Sioux by Royal B. Hassrick casts a little black cloud over my passionate nature.  :)

I quote, "Lovers were never to be seen holding hands, and man and wife never showed any affection in public.  There is no intimation here that the Sioux failed to know all that is necessary to know about the intimacies of marital affection, but this knowledge could not be bandied about.  Any overt expression of affection would be uncouth."

The author further states that in events where women and men were both in attendance, they sat separately, with the women keeping their eyes downcast and whispering only to their neighbor.  Likewise, the men did not exchange glances with the females as modesty and reserve "were the essence of fortitude."

It sounds to me that what went on behind the closed tepee flaps shall forever remain secret, but the fact that it wasn't uncommon for young married couples to spend years with their elders might have provided less chance for intercourse or romance of any type.

It's great to be a fiction author.  Although I can guarantee most of my facts are historically accurate, I cannot with any certainty say that kissing was indeed a custom practiced in private by the Lakota.  I hope to get an answer from someone who might know.  :)  Feel free to share any resources here in the comments.  I think we'd all like to know.
