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."
Nicolás Durán has two unsimulated sex scenes in the film, one receiving a fellatio by Constanza Moreno and the other with Sebastián Ayala. On the first one he said, "There is a little bit of nervousness with the first sex scene because it was colder, it was about five-thirty in the morning and we had to shoot the scene now. I was afraid it wouldn't work because it was outdoors. But everything went great. I felt super comfortable at all times." On the second one, "There was a bit of nervousness because of the fact that I am not gay and if you saw my penis super erect in the heterosexual scene, how can I not be seen like that in this scene, if Jesus is supposed to like the friend. There was a little fear because I didn't know the gay sexual world, I talked a lot with friends. That's why we became super friends with Sebastián Ayala, because how could we not have enough confidence to touch each other, to feel each other? It was more the work of having the confidence than the nervousness on set. We did the scene in one take, although it was very long, so we were already super prepared."
