Thank you for the brilliant answers, and I am glad it has brought the issue of organ donation to the wider audience. I had also wondered, like Luther, about men who must have given blood, some for many years, with undetected Pca.
Item (1) - risk to a partner, is answered. Thanks Lyn.
I can see now, with the help of your responses, that item (2) has two separate parts to it. You can get in a bit of a tiz sometimes and cannot see the wood for the trees.
I can see now that mentioning the Pca does not automatically infer or suggest anything further - though I am not seeking sympathy either.
At the moment I am on Active Surveillance so apart from my biopsy day in hospital, which was before we met, there is no evidence of my condition.
If the subject of sex does arise (no pun intended!) your point, Lyn, about the other person possibly having their own issues is well taken. I should not be so self centred.
Mo, your answer makes perfect sense and is very helpful.
Thank you all for your speedy and valuable answers and support.
David
