I have often thought the same way but, like Annae3221, I'm not sure that I would have the guts to go through with it for many of the same reasons.
What I do wish is that, when I was single, I had had a greater understanding of the signs of ->-bleeped-<- in my life - an understanding that wishing I'd been female, fascination with and wanting to dress in female clothes, wanting to play with the girls at school and unease when trying to form sexual relationships with women (although being sexually attracted to them) were all early indicators of how I may feel later in life. Whether that understanding would have led my life down a different path, I can only wonder although, if I'm honest, I think that the lack of many of the TG surgical procedures such as FFS & VFS that we now take for granted combined with the general view of ->-bleeped-<- at that time would still have made me try to surpress things.
