The sex scenes in this movie are totally real, there is no prosthesis. Director
Fernando Guzzoni explained, "Regarding the decision to film and show, I also felt that the film could not be modest, I could not make a suggestive thing and stay halfway and try to appeal to a generation or to some characters in particular that have immoderate violence or sexuality and be conservative when it comes to filming it [...] That's why the first thing I did was to tell Nicolás (Durán), or Sebastián (Ayala), or Coni (Constanza Moreno) "there are sex scenes that I want to be explicit, I want to see genitalia". Sex is genital and I don't think there is anything dark or ominous in that, that is a cultural construct. I thought it was nice to show it, that was the decision. They are brave actors, generous people with me who understood that this was not an arbitrary decision or a whim. It was at the service of a search."
