I went down a pipeline from more standard to anthro and maybe a little less than anthro. I know I have weird tastes but I teeter on that line. Maybe one day I'll wake up sick enough to embrace such a thing but as far as I can see, that's (probably) not too soon.
It depends on my mood. For discussion, I don't count "monsters" as bestiality. Like, in my mind it has to be really simulating a real animal and real animal cognizance level
