@Fantasticmissfoxy I can't speak for Emma on the programme of course but in answer to "I felt bad for Emma especially as I didn't feel that anyone had been honest with her and said that if the main aim of the surgery was to allow her to get physical with another person, that being a post operative transgender person would narrow her potential dating pool to virtually nil."
I don't think your take on it is strictly true either. Trans people do find sexual partners and romantic and life partners. Yes, indeed the dating pool is considerably smaller than for non-trans people. However, Emma made it clear she was attracted to males and it seemed she was not able to pursue men as a man. I think confidence, happiness and self-acceptance of the person oneself would go a long way to making relationships last, (or even get started). And Emma seemed to lack these.
However, by the end of the programme Emma presented as a considerably more confident and happy person and for a 45 or 50 year old, really very well turned out.
So I think the truth may well be somewhere in between the two extremes. I'd also imagine that as a male Emma had zero chance of getting close to a male, evidenced by the fact she was a 50 year old virgin (nothing wrong with that at all, but it was clear this was not what she wanted.)
She had not left behind a heartbroken wife or ex partner, her choices affected only her really. So I think she had much better chances of being happy later in life than she had up to that point. I hope there is a follow up and we see Emma in love. Plus by being on a national TV programme about this topic she will almost certainly be honest with people she meets about her past, which again, feels (when safe to do) like a good recipe for a good romantic or sex life.
But pretty much all the rest of your comments I agree with.
