denpends on what kind of school it really is, if it's like nsl41288 says, just learning about and enlightening upon all the various forms of hentai, something like specialized art studies, i probably would if it ensures me a good job and get me set for life.
if it's just a normal school, but only where u get to fuck the female students or teachers whenever u feel like, i would consider that too.
but as Arizth said, if it's a recreated scenario from Discipline or Bible Black(where strange witchy horny bitches gathers to destroy mankind), no way in hell is any man able to last very long, i mean, u'll have to have infinite loads or somthin.
it all depends by what u mean by a Hentai School.
