Typically i'll read some furry stories or look at illustrations. On a very rare occasion there's non-furry illustrations i like. Tried stories about humans and it just...isn't as interesting? Rarely i'll watch some irl stuff if it really appeals to one of my kinks. Then the urge is gone for like 6 months or a year.
It's honestly kinda frustrating at times because if someone sends lewds and i'm just not in the headspace it can be awkward to express that they're very nice, but i probably won't enjoy them any time soon.
