I have a MTF deep regretter friend who suffers psychological terrible  deeply and wants euthanasia .....but doesn't get it (in Holland that is)
The evaluations  of his first psychiatrist describe  clearly 'no trannssexuality, but  aversion to his(her) manhood'
The second psychiatrist of course read that but still gave (nowadays) him permission for having SRS because he insisted on having that, for obviously the wrong reasons.
Very, very sad case....he detransioned, more or less successfully because he makes a good looking man but that's not enough.
He's very aware he's actually  a man and misses his male parts desperately....not for sex but as an integrated bodypart.
He sounded like a wounded animal the last time I spoke to him on the phone....terrible, terrible,  but the worst thing is he insisted on  having SRS....back then...
There's no way to help him or to comfort him...alas
