I watched this documentary on Hulu and it is about a 15 year old boy with "mild autism." The description says he was not diagnosed until after the filming of the documentary, so naturally the film makes no mention of autism or Asperger's, but it is a good film following Billy as he expounds his views on life, and struggles to find love.
This is the trailer:
