It is so common I remember it being a little jarring, but was pleasantly surprised, hearing Alfonse in FMA voiced by a real boy Aaron Dismuke instead of a woman. Its so normal that when I googled the VAs name to make sure I got it right the article that popped up said as Aaron had aged out of the role in Brotherhood he was replaced with Maxey Whitehead (♀️) to be more accurate to the manga.
