Me too, but the retarded Patrons voted against it. The question was left open ended, and I think half the Patrons probably thought that going to the boy's school implied gay stuff.
There are enough reasons to vote against it without being "retarded" (aside from the fact that calling people retarded for having a different opinion is questionable in itself).
One, as someone else mentioned, that most would rather have the current game finished before any Spin-Offs or other games get taken on. Personally I feel like progress has been somewhat slow as it is (not a complaint, just an observation) so taking on another game would probably mean neither gets any meaningful progress at all.
Also a game about a male headmaster in an all-female school with strong focus on Male domination over the girls draws a different audience then a game with a female Headmaster in an all-boys school with a strong focus on Female domination over the boys would. Of course there are people who can enjoy both (as you presumably do) but I'd reckon most players who enjoy the aspect of male domination aren't necessarily interested in the reverse setting..
