Ha! I don't even know how to. My friend Messy Irina does, and she makes some pretty good ones. But, she doesn't do mud. Boo hoo! From that profile picture and your moniker, I assume you do like mud. Anytime you want to make some of you covered in mud, I assure you I would love to see them.
I tried a couple of times. Some of it was good. Though I think I need to rethink how I'm placing the Target, and who the target actually is, and stuff.
I don't tend to upload WAM pictures of myself where my face is visible. I have once or twice played with uploading pictures where it isn't, and then seeing AI's guess of what I might look like.
I've done something similar to what @asdf describes: feed WAM selfies to an image-to-prompt service, then change the prompt to describe a woman, and hand that to Nano Banana 2. Since that tends to replicate the cropping of the original shot I then prompt with 'pull back to show her face' to get a wider shot.
ETA: Another thing I've done in the way of "making AI WAM of myself" is creating prompts based on situations that really happened to me, but "starring" an adult AI-generated character (prompting to make her a woman) instead of me - that's what the animated images are.
