it's instinctively uncomfortable to shit where you sleep. In nature animals generally find a toileting place away from the sleeping area.
I post this in every thread on this subject, but I heard of a man with an unmodernised house with outside toilet who regards people who have toilets in the same building that they cook and eat as disgusting.
I suppose you are just a slightly less extreme version of him.
Do you feel uncomfortable every time you stay in a hotel room? (I think they all have en-suites nowadays.)
I don't love hotel ensuites, no, but its the lesser of two evils when compared to sharing a bathroom with strangers. I prefer it when the doorway to the ensuite is off a corridor from the room doorway before you hit the main room, rather than opening off of the main sleeping area, so it feels more like a separate, private bathroom.
At home, I'd prefer a bathroom away from the bedroom than directly off it.
