Honestly, no one (boys or girls) has really even asked for their own space. My oldest son didn't mind sharing a bedroom with his little brothers (even after he graduated high school and was in college) as long as he had a space (the parlor) to kind of call his own. All of my kids were over 18 when they got bedrooms of their own and only as we had space for it. One thing I have tried to do from the time they are around 14 or so is create personal spaces that are theirs alone - from locked boxes for their stuff to items that are only theirs and must be asked for in order to use (and no one is guaranteed their sibling will let them use said thing). I want to teach my kids generosity, but I also want to teach each of them to respect other people's things. Hopefully, that answers your question! :)
