And now for something completely different, yet related.
Anyone heard of a Brazilian theatre group called Uzyno Uzona ? They perform naked on stage, including simulated sex, and, sometimes the real thing. Oh, and it is cultural, so it's not regarded as porn :-) One actress, Anna Guilhermina, eventually got pregnant on stage, continued to perform naked during her pregnancy, and was apparently immensely proud that her private and cutlural lives became intertwined in this manner. The classical 'my life is a stage' etc. There are lot's of clips to be found on the internet if you google Uzyna Usona.
