Basically, I think anyone who does this is in a do-or-die situation.
I wouldn't put up with all the sh*t I get for being trans unless the alternative was to go cuddle up to a bridge abutment at 140mph.
This isn't something people do on a whim.
I just woke up, and I'm really out of it, so this isn't the most sensical writing.
Still, if you think this is a bad idea, what would you have us do? What about those of us (myself included) who were born inbetween and only assigned a gender via a surgeon's knife? Should we just turn on the TV and suck it up?
I dunno about you, but a big part of being alive for me is to make things happen, instead of worrying if I'll "really" be happy.
As I see it, happiness is a byproduct of function, and I do not function as a boy.
