I thought it made sense for my body to match my brain. I didn't need the surgery as desperately as some do, but yes, I wanted it. At the time, 45 was in power in the States and our official opposition party was trying to make itself a clone of the Republican party. So, like
@Athena, I wanted to get it while the getting was good.
I could anticipate a time when genital checks might be required to access certain spaces. Having to submit to such a check would be bad enough, but failing it would be much, much worse.
Plus, I had no particular use for my old plumbing, and losing it would not be a hardship.
All of which reinforced my vague idea that I was pretty sure I wanted it. I had the surgery 6 years ago (the week that covid shutdowns began) and I have had no regrets.
