Added a high lora for 1.1 as well, which is 50 epochs, does not need to be used at all times but can be helpful in certain scenarios, suggest weight of .5 to 1.0. Details of high lora impact down in the testing section.
Updated to version 1.1 which is 60 epochs(double the previous one) and should function well at in a weight range of 0.75 to 1.25, examples below in testing section.
This is a fairly simple low-noise only anus lora. The goal was to generate realistic looking anuses in the right spot, that aren't massively gapped or abused, when one is not visible in the starting image. In particular this was aimed to work in conjunction with my pov face sitting lora.
Prompt is simply needs to include the word anus somewhere for this to kick in. However, WAN seems to often have no idea where to put buttholes so the following helps a lot:
A woman presents her anus. Her anus is directly above her vulva.Obviously if the subject is on their back describe the anus as being below the vulva. The lora should be able to add some specifics around what the anus looks like such as:
a small round anusThe anus is pinkish in colorHer anus is centered, slightly puckeredGiven the training material for this often had both a anus and vulva, you can use it to control the shape and color of the vulva too but I've not tested that extensively. Critical keywords are vulva and labia in terms of prompts.
Testing
I tested this using base WAN 2.2 I2V Q8 and the lightning loras. Nothing else in the mix so i could get as good an idea as possible of what WAN knew vs was introduced by the lora. I decided to test both high and low loras at different weights with each other. The results are below in the grids(final frame and 4 second frame). You can see that while low lora alone does ok, it does produce a lot more detail with the high lora in even at a low weight. I've tried to minimize the motion in the videos and i'm not sure if that'll have a negative effect yet, so please do shout if it does. That said, high lora alone makes for some very odd bits so i'd avoid that combo! Good luck and happy butt testing.

Dataset and Training info.
Input data set was 167 videos all pulled directly from reddit (you can guess the name of the subreddit). Batch trimmed to just the first 3 seconds and capped to 16 fps.
Data set was auto-captioned using JoyCaption Beta and DarkAges 70b.
Low Lora training was done at 512 for 60 epochs, 1 repeat and batch size 2 using diffusion pipe. LR was 2e-4.
High Lora training was done at 256 for 50 epochs, 1 repeat and batch size 6 using diffusion pipe. LR was 2e-5.
As always still not sure i know what i'm doing yet and open to feedback!

Can this be used for men, with testicles or balls instead of vulva?
I mean i don't see why not but i've not tried. You'd probably need to include a lora that knows what testicles/penis means as well though. I'm sure someone will try soon enough!
@imb101 Thank you. I don't know if having "woman" as a keyword causes any issues with using it for males. In the other comment thread you suggested that you will train this one more. Is it possible to make it functional without the word "woman" as part of the keywording?
I have used loras that have woman and female in their keyword phrases/sentences but I have been wondering if training loras with those keywords limits/impacts their usage with males.
@ss9999 The challenge will be it's using all source material with woman, which is super easy to find. For extra training I wouldn't be changing the underlying dataset or captions, just pushing it through the trainer more times maybe at a different learning rate. That said if you can find me a decent source of men butt/anus vids i'd happily throw it into the dataset and maybe start making a version 2. it'll take time to make as i'm training on my local hardware. For men you might also need a high noise lora as base WAN seems to have no idea what a penis or testicles are.
@imb101 Thank you for the offer of letting me submit some male footage for your training. I will see if I can find anything.
Finally a new anus lora, looking forward to trying this. Have you tested with any sex Loras?
I have not, i wanted to test it with nothing else in the mix to ensure it was doing what was expected. That said the whole point of only using a low noise lora was to make it easier to plug into existing lora stacks. I will give it a try when i get a bit more time with some different WAN mixes and loras. I do think it needs more training honestly as i shouldn't have to crank it to weight 2.0 to get certain results.
I will test it out tomorrow and feedback. We are in desperate need of a good anus lora as they always seems to go missing.
@Justing1234 Especially those that work with balls. I struggle with Wan because I end up with feminized men (not just in terms of genitals but also in terms of the shape of the hips and buttocks) who, if they have an anus at all, have female anatomy below that. And usually, Wan (with the loras I've tried) substitutes female anatomy for the anus and places it too low.
Did you really do that? this is the most useful Lora on this site. Please accept my deepest respect.
you are doing god's work
I don't know why, but using this lora requires an extremely high intensity to take effect. In most cases, the intensity needs to be set to at least 0.85, and the angle and position of video should be similar as the training material, to see anus. Excessively high intensity will cause damage to the video quality. Anyway, thank you for filling in the gap in the field of training anus lora.
Yeah as i said in the summary, it needs more training. I'm thinking at epoch 50 or 60 it should be usable at a much lower weight. It'll take a few days to get there as my training rig is really only available overnight.
Thank you for taking action on this matter. Until now, no one has cared about drawing anuses well and correctly. It needs work, but it's a good start. Best regards.
