Not only lives, but how many people change their fucking mind? Why go for something permanent, at such a young age, when one may realize later on, "Hey, i feel different/that was just a phase/etc"/
I do recall, not long ago, even ADULTS had to live a life as whatever gender for a period of time, at least a year if I recall correctly, before getting surgery, and possibly also hormones.
Any young under-18s that fuck with their biology will find later on, if they, "Change their mind", that they already missed out on some important growth.
And to be cliche again, since I saw others post about it elsewhere, how is it tattoos are still, "Wait 'til you're 18" but not this shit?
