Model description
This is an improvement on my original Super Cockskin Lora - /model/1106422
This model is intended for creating images of nude intact men.
This model offers many improvements over the original model. I'm still committed to making improvements.
Settings:
Sampler: I typically use Euler A + normal
Steps: 30 steps has been best for me. Sometimes going lower will lose the concept
Image size: 1024x1024 or a similar equivalent size with other ratios
Strength: 1+ (it can go a little higher without overdoing it). Sometimes going up a little like 1.1 shows the concept better.
Tips: Use both your clip-l and t5xxl. You can pull up one of my posted image and click on nodes to paste it in comfyUI for an example of what nodes I'm using and how I'm prompting my clip-l. From what I know about flux you can prompt with tags in clip-l and with natural language in t5.
Trained concepts. Please note that not all concepts are 100% understood. Prompting will have a great affect on the success:
Nude men - you don't need to prompt penis. Nude man by default should have a penis.
Erect men - erection, boner, erect penis were used. Erect penis is the most understood, but doesn't prompt well. The erections show up more with other actions.
Specific anatomy - foreskin, glans, shaft, scrotum, urethra - try "color coded anatomy photograph", "blue foreskin" or something like this to kind of test what it knows. It only has a weak understanding of most of these.
Oral Sex - the trigger words fellatio, blowjob, oral sex were used, but penis in mouth is the most understood. Tongue in foreskin, biting foreskin were used but it doesn't usually have enough detail to tell. You have to be SPECIFIC ABOUT POSITIONING. Just using the trigger words isn't going to get consistent results. A standing and a kneeling man gave me the most consistent results.
Anal Sex - this was trained but I haven't had any success yet
Masturbating - Masturbating erect penis, penis in hand were used. "A nude male masturbating his erect penis. Penis in hand." - Rubbing penis was not used but seems also work
Masturbating with fleshlight
Anal fingering - doesn't really understand anus or butt hole well. You might get lucky though
Self Suck - Autofellatio, selfsuck, penis in mouth were used but the action doesn't look natural
Cum - Cumming, cumshot, semen, ejaculating cum, - these were used but doesn't look natural and often gets skipped.
Pee - piss, pee, urinating were used - doesn't look natural and often gets skipped or has the wrong color
docking - this is a tricky concept, try docking penises
Inserting in foreskin - finger in foreskin, touching foreskin, penis in hand - these are phrases it was trained on, but doesn't work consistently. "Photo of a nude man with his index finger touching the tip of his foreskin", is more consistent and will usually push it in a little.
Holding foreskin - intended to be like tugging or pulling but misses a lot. The other terms got confused too often so this one seemed like it would work best. "Stretchy foreskin" wasn't used in the training, but seems to help flux understand.
Hairy/very hairy. Also try hairless.
Anime & comic art - During training the anime images got worse and worse as the photo style bled into other concepts. I added anime and comic art regularization images to try to bring the concept back in. I personally think its a bit better than the original flux's anime style.
This model is done training. It got a little overbaked towards the end. I'm still working on making improvements.
For anyone looking to try to recreate a similar model, see my tips:
This model was done with 4 network rank, 4 network alpha. Going too high seems to make it learn faster but less flexible, IMO, and overbakes quickly to look like crappy photos
Proper captioning is key to learn the concepts. The main rule of thumb is if you want something to be default and baked into a concept, don't caption it. For example if you want all the nude men to have flaccid penises, then on your basic images of just a naked guy standing flaccid, don't caption the penis at all. Only caption the penis in non default images like erect penis.
This photo was trained off of mostly old or very low quality photos. If your image sucks, make sure you to caption that its blurry or old or low quality photo. Then when you actually prompt your image you don't use "blurry" and it will be more likely to have everything in focus. That said, blurry images can still bleed into concepts. Also important to caption if it is close up or not. If you don't, you will be more likely to get close up images by default.
You can kind of color code anatomy to help add definition. In gimp you can add a layer to the image with transparency, color something blue on that layer, then merge it down. Export it as like png to your img folder (i had a separate concept folder for color coded anatomy). It kind of bakes out a little, but it helps string things together. Keep the original with its regular captions still.
For example - "color coded anatomy photograph of a nude man. The penis is blue." OR "color coded anatomy photograph. close up image of an erect penis. The foreskin is red. The urethra is white. The scrotum is green." Or "the anus also known as butt hole is blue" (not quite sure the best way to do AKAs in flux).
It does seem to bake out overtime but retains the general location of everything. Otherwise when I prompted anus (after over a dozen epochs) it was still pulling up images of puppies. But one or two epochs with color coded anuses and it was mostly learned.
I read that there was some kind of heat maps or something in these AI models and that at some point you may be able to have more control, but for the time being this is kind of a hack that may help. It is similar to masking, but doesn't block out sections of the image.
When you go to prompt, it will not show the colors on the body parts unless you specifically prompt "color coded anatomy photograph." and isn't going to bleed into the default generated images (unless maybe you have too large of a collection of these color coded anatomy photographs.)
This model was trained in batches. I started by using a huge 650 dataset of images for the first few epochs. These contained all concepts. During training I would save the state. Every so often I would stop and cull images I no longer needed and continue the training.
Some images kind of held this back. For example, the aesthetic I was going for was to have the opening of the foreskin visible, but many of the images I had were taken at an angle that hid the opening. So now the model will often still hide the opening at the wrong angles like straight on.
I did not use regularization images in the regularization folder, but I did add regularization images in folders. I had an anime folder, comic art folder, etc with a handful of images to retain those styles. Otherwise they start to look more and more like photo style.
All of that said, I am working on another model with a slightly smaller dataset, but this time instead of doing all of the concepts at once I'm going to work from basic to complex in stages (solo male nude -> erect -> bodily fluids and touching -> duos/ sex)
DM me on here or on Discord if you need help with a similar model on Flux. I'm not a pro but I'll be happy to chat about it.
