You don't have to tell anyone about it. Out of sight out of mind as they say.
I think of myself - strictly personally/internally speaking - as a hybrid. I'm fine with that. I know my biology presented me with certain average advantages as well as disadvantages. The female brain has a knack for better memory association and recollection for starters, because rather than compartmentalizing things it tends to link them more dynamically and easily. I know I have this ability AND the ability to compartmentalize now, thanks to T. It can multitask better, I have that... AND with T I get the added ability to focus as well. Can pick and choose. I might be smaller than the average man thanks to my biology but that just means I'm cheaper to keep myself fed. Etc. etc.
In many ways I've got the advantages of both sexes thanks to this situation as well as the ability to pass as either of them if I really want to. Looking at it from a logical perspective, advantages are better than disadvantages, and I have more of them than before. I like myself and I like being in powerful positions as opposed to less powerful positions. As it happens, being what I am puts me in a variety of better positions, provided I know how to utilize myself and my talents properly.
Being a normal man or a woman? Meh. I'll happily be abnormal provided I can manage the risk of being so and turn it to my advantage. So.... being what I am doesn't keep me up at night. The philosophical and ideological connotations got left in the dust. Truthfully, I'm apparently a female homo sapien running on male hormones, with the capacity of understanding more broadly than the average person what being a man or a woman is hormonally and socially all about through experience. Fundamentally we are ALL nothing more than a consciousness in a meat suit. I don't read much deeper into it than that because that gets into the territory of mysticism, even zealotry, about what a man or woman "really is". Nobody knows, nor can compare precisely what being a man or woman is because we only know what it's like to be ourselves. We have no idea what some other man or woman actually, truly feels and whether it is properly similar to our own experiences. That said, what's the use getting upset about how "real" or not you are or feel? You'll never know. Nobody will ever know. Except that you're here and alive.
Sure, being treated "authentically" has its importance when we talk about how one is treated in the social sphere. There are risks, alienation, ostracization and being treated differently by people from before associated with people coming out. That's a legit concern worth thinking about, if you think there are risks. But the metaphysics of the matter really don't matter when you realize how little about anything is ever confirmed for us about anything in life, or from other people. When was the last time you got a full appraisal from someone else of exactly what they thought about you? I don't know about you but for me it's rarely to never, and usually it's only when people have some trivial complaint. It reveals how little they know about you anyway, your internal self, and motivations. And they'll never really know and even more likely probably won't be all that interested in the details. People I've known all my life and who are close to me are not interested in the details. Not much point in me getting bogged down thinking about what they think, either. It's a waste of time in fact, I believe.
The only thing you should definitely be doing is making sure you have a good mental relationship with yourself and what you are. If you have that? Good. Then go get on with life and try to enjoy it as much as possible. It's short.
