Indeed, with Patreon, for this sort of game it's not "if" but "when" and actually more like "any moment now". I am not a fetish porn game dev, but if I would be, I would never for a second bother with Patreon at all. Just go Subscribestar, and hope they maintain their current laissez-faire policy. Oh, and watersports/latex/electro play FTW. Not that I would mind some needles either...
What is not really being acknowledged is a Patreon account can be taken down by a single complaint because of something so simple as "You have allowed the landlady to be renamed and therefore have broken our no incest rule.". Patreon is actively banning anyone that might think about breaking the rules and they will actively remove themselves from adult games entirely because "who needs income when you have principles?"
I like the look of your game and I hope it goes well for you.
