Let me preface this by saying I'm not even 100% sure its a manga. It could be an anime or light novel series as well. Anyway I read the synopsis somewhere in the last few months and to sum it up in one line it was something like the protagonist is just your every day high school boy and he's basically kidnapped off the streets to be enrolled at a special high-class all girls school just to teach them about peasants (and possibly men? I forget).

If anyone could identify it based solely on that I would be very grateful.

Perhaps It's Ore ga Ojou-sama Gakkou ni "Shomin Sample" Toshite Rachirareta Ken?
