When it comes to preferences, I wouldn't say I have any hard limits on either way, whether including or not. Still, a couple most notable ones;
Fandoms and oc - I generally like fandoms more than ocs, since to me it's easier to imagine the roles when there's a concrete reference. Ocs also feel a lot more personal in a way, which I'm not sure I would feel like doing with just about anyone.
Furries - they just don't do it for me. I mean I'm not pulled out of it immediately if a furry is included, but I just don't see the appeal of fur-covered body and weird snout-face. When it comes to "monster girls" and humans having some features on the other hand, I see that as a plus. Weird?
Privacy and public - Public stuff, and stuff that includes more than two participants, in general, is heavily dependent on the mood. Threesome and foursomes I can more often than not get behind, but in public or with others watching not as much. But still, like with furries, not an immediate turn-off, sometimes even a turn-on, but those moods are not that often.
Futanari - always a plus. Males don't usually do anything for me, since when compared to females, the voices and different body types are just boring, with the dick being an exception to that boredom. So, futas are great.
Here's the Fandom's I'm well versed in;
