Yeah the partners are mostly a cosmetic option at this point (but I want to make more that you can unlock after doing a quest for them).
There is an option in the settings panel to enable / disable the Futa characters, but I can add an option to turn every partners into Futas as well, just in case picking a partner becomes important at some point.
I'm still working on the Discord server, you can check it out here: https://discord.gg/6Qj7KFMt
It's rather empty though, I'll make a proper announcement tomorrow
