I love living with DP in every way but this. If I could choose - I'd have my own private bathroom. Somehow very private away from rest of the flat, maybe through a walk in wardrobe or something? Dunno how the configuration of space would work.
Our one and only bathroom is a windowed en suite, so guests have to go through our bedroom which I also dislike.
I hate shitting in a shared bathroom, where someone goes in soon after me, it makes me want to crawl out of my own skin as it feels so un-private. I just hate it, I know everyone shits, it doesn't make any difference.
