In the interview ,which I honestly think you should’ve shared in full, Nicholas talks about how he and Graeme were actually pretty comfortable shooting those intimate scenes. In that part, he mentions how the director asked them to hug, even though they had literally just met, so yeah, it was naturally awkward at first.
He also says that even off set, they tried to stay in character and behave like a real couple. Nicholas even mentioned that he once tried holding Graeme’s hand while they were out, just to see how it felt.
From the way he describes his approach to those scenes and the whole experience, I picked up on a certain sense of fluidity to me ,but that’s just my personal opinion. He definitely seems very comfortable with his sexuality, though.
Anyway, if anyone’s curious, here’s the full interview.
