I suggest either a warning or a toggle on-or-off switch in options for Futa and Gay content to help player avoid that content if they don't want to see it.

There’s already warnings both inside the game(As soon as you boot it up, as soons as you finish all the content with Nora, it tells you that there’s only gay content left in the update and that if you want to skip it you should save there.) I also made sure that I’ve made plenty of warnings when promoting the game. If you are still unsure, just avoid Vexx after the initial conversation and you will be golden!
