Why do humans tend to sit with one leg over the other rather then both legs down?

Question

I would of thought biology would like us to be symmetrical for maximum comfort. But after sitting down for some time humans tend to put one leg over the other? Is there a biological reason for this?

I do it because it’s soothing to feel my knee push my calf out of the way and hold pressure against the inside of my shin. I do it laying down too. I fall asleep like that quite often.
