This LoRA adds standing @nal concept to FLUX.
You want to start every prompt with: "@nal sex concept," Then choose one of: clothed/nude/clothed female nude male/clothed male nude female," Then, "a woman is getting her ass fucked by a man, on the left there is a standing man, on the right there is a standing woman, the man has his penis inside the woman ass, @nal sex, fucking ass, penis in ass, breathtaking, award winning photography,"
Replacing the @s with As.
I also add on the end, "everyone has perfect anatomy, and there are (no detached erections:1.4) or watermarks or web urls. by Steve McCurry, her head is placed correctly on her shoulders."
