Femboys aren't my thing. However, if one person is asking for them, there would be others out there wanting them as well.
Whether or not the dev wants to include them, is their own choice.
And who knows, having some femboy getting busted trying to sneak into the palace, ending up in the dungeon, and getting chained up and whipped could actually be a fun little scene.
Just remember, you can't catch "gay." So if there is a scene between two dudes, it won't kill you, or change your life in any way. Except that it would be one less opportunity for you to masturbate.
Or, maybe you would...
