Klein PP [Uncut Flaccid Penis] - v1.0

NSFW

Quick training for Flux Klein 9B - Uncut flaccid penises.

Trained on about 60 pics for 2500 steps (Yes, Klein trains fast and very easily).

Works great in both T2I and Edit mode (I'm not responsible for what you'll be doing in edit mode, please keep it clean and respectful).

Trigger words: "Flaccid penis", "Large flaccid penis", "Foreskin", "Glans", "Large testicles", "Testicles"... etc.

Enjoy!

Training settings:

Trained using AI Toolkit with default settings. The only thing I've changed is to turn on Differential Guidance and set it to 4 instead of 3.

Training was done on a dataset of about 60 images manually captioned, around 20 close-ups, the rest full body.

Dataset was flipped on the X axis.

Amazing work, as always. Did you train this using the default AI-Toolkit settings? Your LoRA is noticeably better than anything else out there. It feels like you’re either using different settings or working with an exceptionally good dataset.

Bump. Can you please share your training settings?

DrakeniJan 20, 2026

"Anything else out there" What are you talking about? There are like 10 other Klein LORA posted, it's a brand new model. All the Klein LORA I've used are amazing. Are you talking about ones you've trained yourself?

love it, and uncut is so rare. Haven't tried yet but I'm hoping it has some control over pubes etc... like so you could have either thick pubic hair to none.

I'll also try my hand at training it but again thank you!

edit seems not working，what is the trigger word？

There is no trigger word, that's not how edit works. You have to ask it what you want, so "Remove the person's pants/clothes and show their flaccid penis between their legs" or something like that.

@DomDomTomTom thanks,but the result still very bad

@GT123 I don't know what to tell you, I've posted an example in the carousel above, it works fine. Not sure what you're doing wrong.

Is 9B better than 4B? I upgraded and I didn't get better prompt adherence, and it has Flux's non-comm license

I am blown away by how good these penis LORAs are ALREADY. Crazy how it's making passable cock in the majority of pics with the right prompt and settings. Flux 2 Klein 9B is possibly the future for NSFW. The kicker is TWO second generations on 5090 too. What a great day! Thank you for sharing!

Love this one! i hope we can have one for erect cocks as well, Thank you!

PrefoJan 21, 2026

this one works for men too (not just futanari) - but i suggest adding a shirt onto the man as otherwise it has a tendency to add breasts if he is shirtless.

This Lora generates the most realistic dicks I've ever seen, nice job!

If you like I could send you some data to add flexibility. Also, if this could do erect while keeping the foreskin, like phimosis, that would be so amazing.

This is the best lora I switched to using klein after being tormented by qwen edit's lora. It works exceptionally well in edit mode, eliminating the need to generate images with one model and then inpainting with the SDXL model. Thank you!

dalvogalboFeb 7, 2026

totally agree! this is so good! i really need an erect penis lora also from him. i tried other loras here but they're not that good. this one works really well in edit mode

Testicles size and glans control? This sounds very promising.
