How much of the male restrictions are imposed by other men though? I mean, how often does it comes back down to male-to-male competition-- whereas females, while still competitive, often have a different approach.
I was thinking about this last night in fact. I was out with bf, my mother, and a friend at a rock benefit concert, and there were women who obviously knew each other and would come up and hug each other, give each other friendly kisses, be much more physical, help each other, etc. While of course the men wouldn't be caught dead doing something like that.
