As far as I understand, cis people don’t necessarily hate their single puberty (or at least not as much, see women’s reactions between puberty and menopause) because they tend to like what they’re getting out of it ultimately. My late grandfather thought high school was the best time of his life and definitely would have redone it if given the chance.

Personally, I’d want to reverse the effects of the puberty I went through (and maybe some transhumanism on top, if that were possible) badly enough, but I’m sure you understand that’s why I’m here. :)
