Rizendy: @Incelebrity Because it's illegal in a lot of the world (animal cruelty laws), and in the rest of the world it's highly stigmatized.

Kolkpen: to add on to that, good luck trying to tell a horse to not absolutely obliterate whatever it's meant to dick.

HotRettas: That horse is the luckiest animal in the whole universe

aryan826: @Incelebrity: also just wanted to add, its actually not illegal everywhere and people do try it surprisingly often, however if you want the horse to actually fuck you, or even stay hard it only last like 4 seconds then they cum and walk off. not like a dog that can go at it for a while then knot and stay there for even longer, with them its like in cum done goodbye.
