The setup in that scene is that MC falls asleep (due to exhaustion/weird stuff in his head), and then he's being used by the nurse in his "dream".
In it you can either:
- continue the dream, which makes this interaction fictional = it's okay
or
- "break" the dream, which makes this interaction real = not okay
So, as far as we're concerned, he did not consent to this - any and all prompts appear after the deed is done. Plus, the scene, albeit dimly lit, is set on the actual hospital bed MC wakes up later on. Not to mention Naomi having the proof of their interaction on her leg with the "second option".
I'm sorry, but either you tag the game properly, or rework the scene.
