Afaik, as long as the owner of said animalistic genitalia isn’t an actual animal or too animalistic of a creature, it should be fine. So many games have that sort of thing with patreons up and running for years. In the same vein, animalistic sex toys would be banned as well but they are not, not even on IRL porn sites.
Ngl, I haven’t gotten too far into the game yet but if that wolf mechanic ends up having a normal human penis, I’m actually gonna be so disappointed
Tbh, I see it as a huge loss when you are going with a interspecies fantasy setting but decide not to utilize the variety of penis shapes and sizes that the fantasy world offers. That way, it doesn‘t all have to be BBC worship crap like most the NTS games here end up being centered around. You would be able to take it to a whole other level and truly make a unique NTS game we have never seen before.
Best of luck
