My father would sleep on the left. I slept on the right when I was with my last two partners. I sleep on the left mostly now because it is near the closest and the door. When I slept with nerissa at coronet I was on the left. When I slept with jean at a brooks even many years ago I Was on the left as well. [EDIT: When I say sleep I should clarify to say I shared the bed. We slept together in the complete Victorian meaning of the word. IE we could have had razor wire between us and neither would have gotten hurt. ]

I am generally indifferent. Though I like being on the right but that was mostly do my back issues. Ie, it was easier to snuggle when I was on my right hand side. I don't know if that still holds true.

It is an interesting thought though.
