You will regret it, you will harm your health - guesses that have nothing to do with reality. HRT harms only reproductive health, which does not matter if you do not plan to have children or have frozen your sperm.
You accuse me of not knowing what you look like and making conclusions about it, but you have not seen what I look like either. At best, you have seen photos of my hair without a face from three years ago.
In my experience, when someone says "You will regret it in the future" - it means that you are right in your bold choice.
