The Third Locker-Room

So I am originally from Sweden, and a quite funny debate has been going on over there lately. I guess most Americans will find it ridiculous since most of y'all are pretty strong to your religion. But listen to this...

So you know how in schools you have two locker-rooms, one for girls and one for boys, well schools wants permission to add an extra locker-room for those who feel that they cannot identify themselves as one gender. You know, those people who feel that they are born in the wrong body. If this suggestion goes through, some school's will have three locker-rooms; one for male, one for female, and one for.... what? "Bimale"(?). Uhm... What do you guys think about this? 

Humans are biologically either female or male (some people happend to be born as hermaphrodite, but I don't think this issue is about them) and we are separated because there are many differences between the two; not only biologically, but physically and mentally as well. So is this third locker-room supposed to get filled by both genders? What will happen in there? I think they probably will need supervision because people will definitely take advantage of the fact that they can see the other gender naked if they go in there. Will people even have the courage to go in there if they feel out of place in their gender or will they be embarrassed when people see them do it? I think they will.

Is the world leaning towards creating a third gender? Or are they trying to unite the two into becoming only one gender? What do you think will happen with this in the future?
