IMHO, it’s a perfectly reasonable thing to want. Maybe you want him to see your pain, and for it to matter to him so much that it elicits a visceral reaction? Wanting to be seen isn’t even a little bit terrible.

Something it might be worth keeping in mind, though, is that some therapists and nurses and doctors and the like have trained themselves to maintain an outward stoicism in the face of pain and injury. (I think it’s something about trying to keep yourself calm in the face of chaos, or maybe it’s just more of the patriarchal nonsense that is so deeply embedded in medical training.) So it’s possible that he might see you but not make a face to reflect that.

Anyway I’m not saying you shouldn’t want it, just offering a thought in case it doesn’t happen the way you hope.
