well, just because you can check yourself out, doesn't mean your not a girl. Could be a very gender neutral outfit, or a non-barbie shaped pilot.
I'd advise filing a bug report on the sub-forum for that, and see if they can add that.
If the game had you going through story as a guy, everybody called you a guy, that'd be a bigger problem with the lack of gender setting. But if the only way you can tell your pilot isn't a girl is because of the look-around feature (that only you can do), that's not the worst problem to have.
