Popular stories?

Okay so in the past month or two inve read a few stories and I realized I kind of like the premise even though it technically makes no sense. An all girls school but somehow the main character (a male) is accepted in and is somehow busted, It's even better if it's like a campus style thing so he's stuck on school grounds year round.
But I'm not a huge fan of castration stories so if you plan on writing it I would appreciate you keeping that in mind

(maybe it's punishment for failing a test or talking in class by the teachers and the class laughing at him, or it's by the students and the teachers just do not care, possibly it was the deal from the principal to allow him to be at the school, or it's even a "tradition" and all of the students are kicked in the crotch every once in a while to "make sure they are not a boy in disguise", or some other reason entirely)
