LTX 2.3 Update:

This is far from perfect, but I was able to generate videos I was happy with. There is no trigger word, just be descriptive. I did not train on audio and I noticed there is an odd buzzing noise. Possible it was because of my prompt, but it might be the LoRA itself causing that. I have been running it at a strength of 1, unless I combined it with the Body Growth/Expansion LoRA and then I reduce it down. WARNING: If you are not running this on your own hardware and are paying per use, I would be careful with this. I was getting a video I was happy with about 1 out of 4 runs.

Update: Version 2 uses 2x the source videos and I baked it longer. I think v2 is better, but still room for improvement. "cockgrowth" is a trigger word. You can also use phrases like "his/her penis grows larger." "his/her balls grow larger."

Makes your subject's cock and balls grow larger.

First LoRA I've done. I'm happy with the results for my first attempt.  I will definitely be training a new version soon with about double the source footage.  I used the workflow cruffsant461 provided for the Body Growth/Expansion LoRA
