I am most definitely NOT the dominant partner in a relationship, but I AM left handed. I choose to sleep facing the wall...actually with my head touching the wall (typically on my left side but right side of bed)...on a side note, I am the only one in my bed, and I find it rather comforting to sleep diagonally (top right corner to bottom left corner, although I really don't take up much room)
*hope I've not confused the planet*
