Mm... I have to say the concept of consent between species that don't communicate in an understandable way is a major issue with me so far as bestiality-as-kink is concerned, largely because it intersects with the idea of rape as kink which, if we're talking consensual rape fantasy, you can argue shows that if non-consensual rape isn't legal due to the harm it causes, then probably/possibly bestiality shouldn't be either unless a definite form of consent from animal species can be confirmed - I don't want to get further into this right now, but you take my point, yes?
