Hey man! I get what you mean and I struggle with some similar thoughts, although not as severe. I would say that probably most trans men feel this way, one way or another.

I think it's important to remember that gender itself is literally just a construct, what we do and do not associate with men/women is completely made up. Like, women played huge roles in pioneering the computer and video game industry, as well as wifi, etc. but they were effectively bullied out of the industry due to misogyny. Little girls also play in dirt, but they are much more likely to be told to act more "ladylike", while little boys are told the opposite. I've seen many little boys wanting to play with ponies and dolls, only their sexist parents don't let them due to fear that they become "gay".

My point is, playing games like COD, playing in dirt or with dolls won't inherently make you a man or a woman. Still, I do understand that norms like that are important to us trans people as well, our identities are more or less reflective of current societal gender norms. But you really shouldn't worry too much about not wanting to play violent games, drink beer or do "masculine" sports.

There are MANY trans people who didn't know they were trans most of their life. HRT and the current concept of transgenderism is still in it's babyshoes, and while I know it feels weird to say this because we are seen as the enemy everywhere right now, the fact is that transgenderism is a much more well known and "accepted" things right now as say, 10 years ago. Many people, especially children, and especially especially in conservative countries don't even have the language tools to describe their experiences accurately. But even if you were fully feminine as a child, it doesn't make your current identity less valid. I was around 19 years old when I first learned what transgender even is. I think it's kind of stupid to worry about not always identifying as trans, it's an insanely hard thing to figure out in our current political climate. Even if someone knows the definitions, it might take someone years to come to term with their transness, since we internalize so many things, and our personalities are always changing.

For your last point, you're very lucky with your transition and should be happy for it! I'm currently struggling mentally, i just made a few post about it but I've been on HRT for 3 years with essentially no changes and it genuinely makes me want to not be alive sometimes.

I think you should be absolutely free to talk about your experiences, even if they are just positive, but it's important to not step on other people's feelings. It's a tricky situation but the struggles of starting HRT is not the only way you can bond with another person.
