I am working on an erotic story that involves a character who shapeshifts into a leopard who is involved with a normal human. I have researched both online and at the library and have not been able to figure out some basic questions that would impact the story.
I have found numerous references to cats, even leopards, having barbs on their penis which "stimulate" the female when pulled out. Whether the female likes this or not seems to be in dispute. If a human touched an aroused leopard penis, would they feel the barbs? How hard/sharp are they?
