My wife and I have a good marriage.  We have been married for 4 years.  However, one of the things we sometimes argue about is where we sleep on the bed.

I sleep on the left side of the bed, and she sleeps on the right side.  It's a queen bed.  I'm 6ft, 180 lbs so it's not a size thing (and she's much smaller than me).  It's just that I feel like I need variety in my surroundings, and switching the side of the bed every few months fills that need for me.

On the other hand, my wife feels like she needs consistency.  She feels like she needs some things to be hers, and one of those things is her side of the bed.  She feels like switching sides violates that need.  

In our first year of marriage I slept on the left side.  Then we moved residences and I was able to switch to the right side of the bed.  We switched without talking about it - I wanted the right side and my wife didn't care (because we just moved).  Honestly I think she didn't even notice; I spoke about it with her recently and she didn't even remember.  Then after another year we moved to our current location and I again switched to my current location: the left side of the bed.  Like last time, I wanted to switch and she didn't even notice.

Now, we've been living in the same residence for 2 years and I'm getting antsy.  I've been sleeping on the left side this whole time and I still am.  I've been asking to switch for months, and she's been asking to keep her side.  She has tried to compromise by switching for one night, and it was nice, but it's only one night and we only did it twice.  She also tried to compromise by giving me the only nightstand, but I don't really need it.  

What I ideally want is to switch every 6 months, but I'm open to different time frames or ideas.  The reason why I'm posting here is because she says that nobody regularly switches sides of the bed and I'm weird for wanting that.

AITA?
