Well, since it just means "normal" there really is no need to invent a label for it because everybody damn well should know what a woman and a man mean. A woman is a woman, a transwoman is a male who roleplays as a woman, a man is a man, and a transman is a female who roleplays as a man, and the latter versions are the only ones who need a label because they are not normal.

Now, in principle I don't have any major problems with people who feel the need to roleplay as the opposite sex, provided they have the sense to realize that they actually aren't a member of the opposite sex because there is no way to change their actual sex, so no matter what they feel like or how well they can do their roleplay or how well they can fulfill the role of their preferred gender in society it still is just roleplaying. So, if they can be honest about that, and not do something like lie about it when it really matters (when they are dating, to their doctors, some jobs...) or try to force others to pretend that they actually are the SEX they aren't, fine, play all you want. When what you do doesn't hurt anybody else I see no problems with it, not everybody has to be normal, and sometimes the eccentrics even can give valuable contributions to society. When a person's mind doesn't work quite like that of most people they may also be able to "think out of the box", maybe notice things others don't, and that can occasionally become useful.

But the eccentrics should be able to accept that they are exactly that. Eccentrics. Not normal.

And they should always be very, very careful about that "not hurt anybody else" part.

Unfortunately, of course we currently are way past that kind of mostly benign eccentricity.
