I've experienced a lot of the privilege that other men have commented on already, but one of the things that was only briefly touched on by Tysilio, I believe, was the camaraderie that men seem to obtain just from being a man. Not only around friends I've known, but in complete strangers, who nod curtly, as if acknowledging that we're equals, or something. Bros that never were, perhaps? Haha. In any case, it's fairly interesting, seeing how going from female to male has given me a sort of 'club' that I'm always in, whether I'm aware of it or not.
Also, not to sidetrack too much, but has anyone noticed themselves acting toward/treating society differently since transition? For example, I've become much more aware of how I look at women in public, as though I'm afraid of looking at them in a way that might be taken as a threat, peep, or otherwise unsavoury fashion. I have no interest in them, sexual preference-wise, but I still find myself extremely aware of how I make even the slightest glance toward them.
