I also have a few suggestions for things you can implement later in your game, if you don't mind :)
1) An "academy" where whores can obtain sex modifier acts or kink traits, but it costs money and the whore needs to miss a day or so of work.
2) Personality traits - Yandere, deredere, himedere, tsundere, etc
3) Appearance/Cosplay traits - MILF, imouto, onee-chan, lolis, student, policewoman, teacher, etc
4) Races - Succubus, kitsune, neko-chan, human, bunny, dog, etc
I'm very happy to hear suggestions!
I was already thinking about something like the academy, although it might take the form of random events rather than something you can access all the time so it doesn't make the game too predictable.
New races/appearance traits are a nice idea, although I want to be careful because the more things a customer might ask for, the less likely you are to have someone who matches, so the harder the game becomes. Maybe further down the line.
Some things (e.g. human/animal hybrid people) I might connect to Patreon goals if enough people are interested in them.
