From an interview with Director/Actress Uisenma Borchu:
"Filmmaker: Do you find the sex scenes in the film provocative?
Borchu: I’m sure some people will be shocked by the explicit scenes. I like sex. I like the intimacy of two people because I think it is the most exciting thing, but it is also the most normal thing. Fundamentally, we are here to fuck each other, so sex should be depicted as normal and natural."
But as I previously stated, I do not trust the use of "explicit" anymore, so we will have to wait and see.
