Okay, I had to update this one. I asked my friend to clarify. So the human doesn't get inside the fake horse mount, they stand alongside it. When the horse gets excited he mounts it, someone has to clean his erect woohoo, then he yeehaws into a giant tube that someone standing alongside the contraption slips onto him. They train the horses to do this. Google "stallion s3m3n collecting" for more pictures. She made it sound like they get a lot in one go, so if we can convince people horse sperm makes their hair vibrant and grow fast, and we find someone willing to clean and collect, we can sell it for $50 an ounce and be rich!
