In case it wasn't obvious from the title, this LORA can be used to assist in generating images depicting a feline penis. It's used with Pony XL-based models, and works with both anthro and feral characters (likely taurs as well, but I didn't test it with them).

The tag to activate this LORA is "feline penis", but "sheath" and "penis spines" are also recommended, and according to the original creator, "anatomically correct" and "feline genitalia" also pair well with it. Though on a side note, while most feline species have penis spines, lions, leopards, jaguars, ocelots, and some others don't --- something to keep in mind if you're trying to accurately represent the species you're generating spicy artwork of.

You should also consider using "knot" and "canine penis" in the negative prompt as well, as the LORA sometimes generates canine features (unless that's what you're going for).

The creator of this LORA is the ever-talented Warvilton, and you can find the original copy here in their CivitAI gallery;
