I haven't seen it here, maybe I missed it but one of the golden rules of being a man is never touch another man other than a handshake if it is humanly possible. I don't even like to shake hands to tell the truth, but I am not really much of a man in a lot of ways. A man also is very careful about touching a woman, yes he loves to do so but will fear being thought of as too forward unless you know the woman very well.
Also a man will almost never keep his knees anywhere near each other. The farther apart the better.
