I'm not sure how "informed" you can ever be about this sort of life-changing thing, but Fionne is going to have to have gone into it as clear-headed as anyone ever could, I think.
And as an adult, if people want to perform not-totally-impairing body modifications, and are informed of the risks as best we can, then I don't think we can deny them, even if we don't pay for them. (Although I think I might have actually donated to Fionne for this a while back - I don't recall if I did or not).
But the problem is that many people seeming to head into this do not seem to be as clear-headed as Fionne, and are not having hard truths put to them sufficiently. Particularly children.
We might permit all sorts of adult things, but we don't have to be promoting them in schools and putting children on a path to them - smoking, tattoos, breast implants, and certainly genital reconstruction.
Anyway, good luck, Fionne.
