Hello and thank you for your concerns.
About femdom, it's already in but you could "avoid" it by not following the story of the character that does it (It's only like playful banter between the girl and the protagonist, nothing hardcore).
About femboy and gender bender, those are ideas that I have for the future but still can be discarded if people are against it, or, those could just stay as gags for the possible characters.
I hope this could clear you concerns
