I really,
really hate to burst your bubble, but AFAIK the main controversy about this film is that it got it's rare 18 certificate in Brasil out of political reasons and not because of it's explicitness. It caused quite an outrage.
According to
this link (use google translate - I did), there are only 3 sex scenes in the film, and only one of them shows an erect pen1s in an orgy (with no penetrat1on of any kind)
