    INTACT ERECT - Uncut Erect Penis (Z-Image Turbo) v1

    I trained this lora for my own fun after countless tries for over two months... The final version took about 10 days to train and I'm pretty happy with how it turned out. I hadn’t seen many loras that do erect, uncircumcised penis, so I thought I’d share it with everyone.

    The lora was trained using approximately 10,000 steps, focusing primarily on achieving a straight erection. I attempted to incorporate various angles in the training data, but faced several setbacks—likely due to the characteristics of Z-Image Turbo as a distilled model.

    I plan to expand the dataset for future versions to improve the LoRA’s overall flexibility.

    LoRA strength can be adjusted between 0.4 and 0.9. Higher strengths yield greater fidelity and detail, while lower strengths offer more stylistic versatility for things like anime or pixel art. Feel free to experiment to find what works best for your creative vision!

    Recommended Settings:

    • Sampler: Captain Flowmatch Advance (for better details and richer color)

    • Scheduler: Simple or Sgm_uniform both produce excellent results. (Sgm_uniform renders slightly better details in realism)

    • Model Sampling AuraFlow: 3+ (step up with 0.1: higher the value, smoother the results, while lower the value likely produces better details.)

    • CFG Scale: 1 - 1.3+ (higher value often produces deeper contrast - unlike the original ZIT model inclined to produce unnatural results at CFG >1)

    • Steps: 9-10 (up to 14+ still produces helpful improvement of details in many scenario combined with higher CFG. It will alter a little bit on each step further than 10, you need to experiment a little bit to your needs.)

    *All of the sample images are generated with Z-Image Turbo FP32.

    This LoRA is unable to generate younger men and skinny bodies. I always get men 30+ and very muscular bodies. I need additional sliders for that. A penis LoRA should not change the whole body.

    Hey Erny, from my test in ComfyUI, it does generate fairly very young characters, maybe you can try to experiment a little bit with the prompting, and try specify the age in your prompts, it's actually quite easy to achieve some hairless twinks. (I can't put the sample images here because it can be quite inappropriate relate to underage nudity).

    As for yesterday, you reported that the lora was unable to generate older guys with muscular body, I was about to reply but you had deleted the comment by the time, anyway I've put some sample images in Gallery section, if you're interested.

    Thanks for your feedback! :)

    Yes, I will try to diversify the training data in future version. Appreciate the feedback! ☺️

    Best Z image penis lora, i tested so many penis loras, but this one is really good for realism, also working well with character lora. For flaccid penis i use Flaccid penis VXT, which is also top tier
