If the stallion self-identifies as a mare, then s/he would probably enjoy being “milked.”
Wouldn’t want to taste what comes out, though.
I am a human woman, so not interested in a horse. LOL!
But if you self-identified as a horse, you, too, could get milked. I wouldn’t try running the Kentucky Derby, though.
Interesting passage in Aristophanes about that. Wasps, I think. There’s a trial, and a bunch of suckling pigs are brought in as sympathy witnesses. The judge asks, “can they feed without the mother”? and the lawyer replies “Can they feed without the father is a better question”. That is about the grossest thing I’ve ever read in a Greek play, so of course I had to share it.
