>>16425231It's too late for you to alter your whole body's genetics by the time you've developed enough to form an opinion about yourself + you'd have already missed out on the events and memories that happen to the opposite sex.
Your body isn't gonna cut off all that meat and regenerate into what you want to be, so unfortunately it's impossible to change your own body's genetics.
What might be possible though is a brain transplant to a genetically engineered and grown body and even then you're pushing sci-fi tech.
Not gonna happen, accept your body and find other ways to express who you are.
