I know this is a highly theoretical subject for me at this point, but I can't help my silly curiousity...
I've seen it mentioned that your outcome voice-wise on T, may be somewhat genetic... is it likely that I'll end up as a exact replica of my brother if I go on T? I ask this whilst cringing, as... ugh... I really, really, wouldn't want to sound too much like him. At 18, he's still got a very nasal, throaty, adolescent sound.
His voice is honestly quite irritating and I'd hate to end up just like that for the rest of my life. Sure, I'd love to be read as male regardless, but I'm kind of attached to the pathetic and possibly hopeless idea of sounding something like a remotely attractive man one day. -- Particularly one who can sing without making others' ears bleed.
I know it's not a guarantee that I'll end up like my brother, but one thing that does cause me to speculate and worry even more, is the fact that right now, the closest I can come to achieving a passing male voice is to sort of imitate that 'throaty' sound that my brother has. If my voice remains 'clean', it sounds too female to my ears.
My only consolation is that my father has a fairly deep voice...
