Thank you for your replies, and the advice you have given me so far. I think that chemical castration would not be the most suitable step for me. I think that I will be most healthy and happy going through with an orchiectomy.
I have a GP appointment on the 8th May (soonest I could get), I have questions already jotted down that should sufficiently elucidate to me what the NHS can do for me. I will update you all on what comes out from that appointment.
So, in the meantime, I would like to start considering HOW I can become physically castrated. I would prefer to have it done by a proffesional, in a clean environment, and in the UK. I am very unsure about doing something by myself. Notwithstanding my fear of flying, I would still be willing to travel to, I guess, anywhere in the world to recieve this procedure. But the closer to the UK, and if I can reach such place by land/sea, would be preffered. Enlighten me then please, my options that best meet my demands
