80% of the games not in the adult section (I don't frequent it that much only found this game cause some guy on a teaching feeling thread mentioned it) on this site are either gay lesbian otome or other out of the norm stuff.
I cant even begin to comprehand how much work the dev would have to do to make this a gender choice game, this game already looks hellish to update with the amount of outfits you have to program into the sex scenes (make POV doggystyle possible pls and add an option to tell priest bot the truth after you lied to him when you go to the church).
Edit: You can reset the church storyline by typing iamacheater in the browser window it also resets that choice
