In case you have the hardware that can handle AI and want to do it locally without using online service

1) As said above install Stable Diffusion Web UI
2) Install custom AI model. The built-in can’t generate such content. Try indigoFurryMix or YiffyMix AI model as start point
3) When printing what to generate use same tags like in e621
4) Using artist name can greatly change how AI will draw picture
5) Simple example prompts:

todex, machine, muscular, dick, erection, balls
pencil drawn, dragon, muscular, dick, balls, dakimakura design
taran fiddler, zoroj, chunie, demon, forest, muscular, dick, balls, erection, oral penetration, duo
alien, balls, dick, duo, muscular, breasts, pussy, male/female, looking pleasured, missionary position
realistic, xenomorph, muscular, anal penetration, doggystyle, duo
Killioma, dragon, forest, muscular, dick, balls, male, autofellatio, oral penetration, sitting
truegraves9, deathclaw, muscular, beach, presenting hindquarters, all fours, dick, balls, anus, looking pleasured, ass up, cum in ass, tongue out
truegraves9, deathclaw, muscular, beach, anal penetration, doggystyle, duo, male/male

6) You can find more example prompt by using tag prompt https://e6ai.net/posts?tags=prompt+
7) If you want to improve the picture you need to experiment with different prompts, negative prompts, different artist prompts, different AI models and etc.
8) Sometimes AI can't generate character you want. For example brooklyn https://e6ai.net/posts?tags=brooklyn . In that case use separate LORA model. It's like plugin for current activated AI model that teaches how to draw that character or thing without using another large AI model

That's interesting.

If you computer can handle it, you can also create your own LoRAs with kohya ss, the installation is pretty straightforward if you follow the steps properly: https://github.com/bmaltais/kohya_ss

After kohya ss is installed you have to run gui-uv.bat in the kohya_ss folder, but unlike Stable Diffusion Web UI when you run the bat file, it doesn't automatically open new tab in your browser, you have to open a new tab and go to http://127.0.0.1:port#_indicated_in_the_bat_file.

When using kohya ss, you have to specify the pretrained model you want to use, so it's possible to choose from indigoFurryMix or YiffyMix AI to train your LoRA.

After you have to choose your image folder which is the folder that contains the subfolder of your images to train. I struggled a bit with this step, but I'll make it clear for you to spare some time.

So if your images are in: F:\training\character\xx_character, you have to select F:\training\character for your image folder. xx is the number of repeats per image, it is recommended to put a number between 5 and 10, so if you want 5 repeats, you have to name your folder 5_character.

It's up to you to select the output name and directory. Once done you click on "Start Training" and wait, wait and wait.....
