I assumed that it wouldn't be accepted on Patreon at all given their vague rules, which is why I only made the SubscribeStar at first. But I did submit the game for review with a description of exactly the kind of content it has (sex with four-legged dragon friend) and it was accepted, and has raised no issues with them in over two years now. But yes, to play things "safe", I am staying away from both human characters and realistic/non-fantasy ferals. The character importer asset exists for people to add their own models in that vein if they choose.
