The biggest difference is architecture. Men's rooms usually have no dividers between urinals, so privacy is achieved by ignoring others. When you start to chat or look at other men, you've infringed on their privacy. You look exactly where you have to look and no where else. Women's rooms have individual stalls. Privacy is achieved by closing the door. When a woman is outside of a stall, she does not feel the same privacy constraints as you or I in the restroom.
For this reason, different restroom cultures have arisen. Men go to the restroom for bodily functions. If another man does more than nod at you, you wonder what's wrong with him. Men's rooms are silent. I'm told women do not always go to the restroom only for bodily functions, but to check makeup, chat, get a break from us, etc.
The problem with applying logic in an attempt to understand this difference is not that logic doesn't work or that women are illogical, but that you are lacking in the necessary basic information before you start to solve them problem.
