Hugs

So I have often noticed that when I go to hug a person I often end up doing a bit of a head bob because I'm aiming wrong. Recently someone informed me that most people go in a certain direction when they hug. Their naturally instinct is to press a certain cheek to their friend. And apparently I go against the main stream in my preference for which cheek. Go figure. So I'm now curious and want to know more.

Which cheek do you present when hugging? (and I mean right or left, not face or butt!) hahaha
I've searched the Internet, but seen no comments or support for this theory online. I'm interested to know more, and the World Wide Web is letting me down. Thoughts?
