What is a woman's private sitting room or bedroom called?

I have one of those and I can say with certainty, its a huge part of why I am happily married for 44 years 🤣

I have a boudoir, my partner of 31 years is allowed in and he loves it as much as I do. We have never sulked in it

SunnysideSyl, it might be what your hubby is thinking too 😉

I like my Den as my private sitting room, my husband like the kitchen as his. my comfort chair is there.

i chose the fanciest word, 😂
