6’6” and 300 pounds? Eh, just stay a dude.
I mean, I’m a guy, but if I had some weird intersex condition where I was genetically male, but outwardly female... short, full of curves, no whiskers, and basically ‘look’ completely female... hell, just hand over the damned bobbie pins and fingernail polish. I’d live my life how I looked, rather than try to chemically or surgically mutilate myself into some weird, androgynous freak. Yeah, when I’d get home, I might plop myself on the couch, light up a stogie, and watch “Combat” reruns, and cater to my inner (and celebate) dude-ism. But that would be it.
But this person did not naturally look outwardly masculine. She has Kallmann Syndrome, which (as the article notes) blocks the onset of puberty (and the resulting secondary sex characteristics). The only reason she had outwardly male characteristics was because she was artificially pumped full of testosterone and other male hormones during adolescence.
So, she did not "chemically or surgically mutilate" herself - she had surgery and treatments to correct surgicaly and chemical mutilations that happened years/decades earlier.
