Does anyone think that there is a very subtle sexual element to greeting people with hugs? I mean if you are a guy and are greeting your friends, you use a handshake. But you will typically hug a girl. I think this is very similar to the "hoverhand" phenomenon, where the guy knows he is not as attractive as the girl, so he isn't sure if the girl will be receptive to physical contact with him. It would be weird or embarrassing if a guy went for a hug and the girl refused.
