It Improves the default dog penis
Add 'futanari' in the negative prompts.
If the drawing style starts to look weird, try removing the '(3D_penis:0.5)' prompt to fix it a bit. Use this LoRa at a weight between 0.4 and 0.6. I wouldn't recommend use it much higher because it alters the style too much. I use it at 0.6 and it works well for me.
