Food for thought : veterinaries involved in artificial insemination most often have to obtain the semen samples manually (esp. common in the case of prize bulls or race horses - good genes are worth a mint, and it’s easier to sell an ice bucket full of swimmers than it is to organize a recreational trip for the whole bull).
It’s perfectly legal, although of course very few vets get off on it ;). AFAIK, nobody bothers them with consent issues.
Maybe you’re just not doing it right.
I don’t think beastiality is wrong, just absolutely disgusting and degrading-- not for the animal ironically but for the human being engaging in it. Anyone who does that IMO has hit bottom.
So this guy walks into the matrimonial bedroom with a sheep under his arm. His wife opens one eye and hears him say in a loud and slightly drunken voice.
“I have to confess that this is the Pig I have been sleeping with when you are not around!”
His wife shrugs and closes her eye and replies. " I think you will find that that is a sheep not a pig you drunken fool!"
To which he retorts
“Shut up woman I was talking to the sheep!”
I’ll get my coat 
Slightly O.T. but when a Human pairs up with a Klingon or a Vulcan whatever isn’t that Bestiality ?
I ask this because presumably those two non human species aren’t even as close to humanity as a Chimpanzee or Gorilla
.
Or have I missed something ?
well, SciFi has established that aliens of every shape and form are hot for human women… with Trek further specifying earthlings will go at it with anything reasonably humanoid that can be determined with some degree of confidence to be of the appropriate gender (and eventually justifying it in that all those species were “seeded”)
But really, it goes to one of the lines of the discussion: if Lifeforms A and B are both endowed with such qualities of sentient consciousness/awareness that they can be ranked as a “person” capable of autonomous moral decisionmaking, THEN valid mutual consent is a meaningful concept in evaluating how licit is their union.
Though there will always be someone who will come up with 5 pages of impassioned rational arguments that can be summarized as: “ick, that’s unnatural”.
So if my dog can talk, I can fuck her?
Good to know!
Sure, but that’s just the first step; once she acquires language then she can give or withold consent, and you’d have to argue before the court that she did so knowingly and freely* (that’s provided the Court allows for the conversion to “dog years” of the age of consent). Why you’d bother fucking your talking dog instead of making millions on TV and public appearances is beyond me, but to each his own…
(* if the court recognizes her as a person, she stops being property…)
The bitch told me she was 18!
