The point is, though, that this thing is a game. And, as a game, it doesn't care one lick about how your character acts, dresses, or thinks. As far as the game is concerned, biologically, your character is male or female, as a human being. The game doesn't have a medical degree.
As far as real life goes, there are medical conditions which can cause you to be both, or psychologically feel that you ended up with the wrong body, or any other number of things.
But this is a game, and programming in things like that is largely unimportant. Its not even a game you pay for, or that you can even pay for. Its here because someone out there wants us to have what they have created, and at no cost.
Also, as someone that has worked on a game before, there is always the List. The List never ends, and is rarely static. As new ideas show up, things end up on the list or don't, depending on what the admin wants, and are given a priority. Things on the bottom of List rarely get done because they're mostly flavor and don't make vast improvements, and things near the top of the list don't always get done in order because they tend to be hard to implement. The List is always there, though. I, for one, would rather get new features done on the list than worry about a butt hurt feeling or two - Especially since this game doesn't seem any bit worried about butt hurt feelings.
