Yeah that’s true, and puberty’s been starting earlier and earlier for AFABs in the past decade or two. If it’s starting earlier then it’s easy to assume it’s ending earlier too. The average age for puberty to start is 10, and the average duration of puberty is five to six years. 25 is not a normal number to still be physically maturing at for AFABs. Not saying it’s not possible, but it’s definitely not the norm. 10-16 is a more accurate number for the majority.
To clarify, when I say physically maturing I mean the development of secondary sex characteristics, which is what puberty is typically associated with.
