I'm going to a private art college in the fall, I am in somewhat of the same situation.
They are a very, very, very open and diverse community, as in on the application, it has boxes with male, female, and transgender.
I've been talking with one of the directors and he told me that since it is a small school, around 1,300 total, that I would be placed in a male dorm. But he strongly recommends that I stay in the upperclassmen dorms, so that I would have a private bedroom in a suite with a couple other people. I would totally opt for the private room, but I want to be placed in the freshman dorm. I would feel much alone in a private bedroom. I spent my entire high school career by myself, so I don't want to start off college that way.
I want to have roommates, but I'm afraid of binding and packing and what not. Especially when changing and sleeping. I would probably just have to explain to him that I am trans. If he or the other roommates, whom I wouldn't have to worry about cause they would be in a different room, have a problem with it, I would just bring it up with the housing director.
I've also never really been around guys before, I know, sad right? I've always surrounded myself around girls, whom in which knew me before. The only guy I've ever been around is pretty feminine.
Though the bathroom is just like an ordinary house bathroom, and there are four people to a suite, two in each bedroom. I don't have much to worry about then.
Sorry, I'm just working through my situation, but now I realized that I shouldn't have any problems!
