"oh they're humping my leg they totally want it!" no that's not how any of this works you mongoloid holy shit.
animals have no concept of consent and are routinely traumatised by people who do actually act these things out with real animals. they are nowhere near the same level of sentience as humans and their only concept of "sex" is "procreate", unlike the heavy emotional side of things humans like to slap on there too.
a lot of places are also keen on the whole "luring" the reluctant animal into fucking them - usually orally - by putting delicious foods on their junk, and honestly, i hope anyone who does that gets the most painful yeast infection/uti combo known to man. having to condition an animal to associate tasty food and human genitals isn't even anywhere near the ballpark of consent and is outright training and manipulation
despite what they might say otherwise, these people dont give a flying fuck about these animals. if they did they wouldn't be sexually abusing them.
yes i am mad
