I used to sleep on the right side when I was young but that was cause I hate sleeping right next to a wall

As an adult though I have always had a preference for sleeping on the left side frankly because every partner I have had seems to prefer the opposite and now after years of coupleness can't really sleep on the other comfortably. The funny thing is that I accordingly now sleep on the same side as my mum did.

So if all the boys I have shared sleeping space sleep on the other side - does that mean that there is some gender thinger going on here?

Interesting
