In retrospect, I regret not having had myself “fixed” when I was younger. I knew I wasn’t especially interested in kids, but I sorta wanted to retain the option in case I wound up with someone who did consider that important. As it happens, that’s never been an issue… and I’m approaching an age where it’s unlikely it’ll ever become an issue.
If the surgery had been just a bit more reversable… or if I had a slightly stronger libido… or if I’d ever done the sleeping-around routine…
Of course it’s still an option. But I’m also approaching an age where future partners are likely to be post-menopausal, so it’s entirely too easy to let that resolve it.
