Is there a way to do things even if your femininity is too low
like can I somehow edit the HTML file
or releasing a cheat or debug option in the future
There is an achievement for having sex 200 times which unlocks an accessory that allows you to take actions regardless of femininity or arousal. Obviously, that wouldn't be helpful on a first playthrough, however, achievements are saved in cookies, meaning that once it's unlocked, all your save files will have access to it. (Unless you clear your cookies)
Debug features are something that I have considered but are not currently available.
