That could be a tough situation to handle. We don’t have any specific transgender policies, but all of our dorms are mixed.
Transgendered individuals identify themselves as male or female based on personal introspection. This has nothing to do with anatomy. On one hand, if a person feels that they are a woman, it would be difficult to argue that she doesn’t belong in an all-female dorm. On the other hand, she might be quite understanding of the other women’s preferences since she is asking them to be understanding of her preferences too. It sounds like this was the case in your situation.
Regardless of gender, if there is an individual who you think will make other guests in a dorm uncomfortable, perhaps it is better not to put them there. Isn’t it better to disappoint one person than to risk making all of the other guests in the room uncomfortable?
Has anyone else been in this situation?
