I'm 34, biologically female, and i'm done having kids. I've experienced a fair bit of life now, and think this is the real deal, that I know my mind and circumstances, and I would like to be sterilised.
Ha ha ha, says the NHS, no way. How can you possibly make that decision? You've only had one child! You're only 34! We can't possibly.
However, there ARE actually people out there, associated with the NHS, that think it would have been fine to make that decision as a child and sterilise myself with puberty blockers? 
I just wanted to voice this somewhere.
