prompting "viewpoint is POV" makes the camera angle optimal. It isn't 100% POV. If you want to have exact POV you need to prompt "Viewpoint is POV from above" You can see it in the example pics.

I literally needed 5 iterations to finally got a working doggystyle lora...

Prompting is very important and the final format of the image.

Use my prompts and then modify them until it suits your needs. Doggystyle is very hard to get clean in Flux 2

Do not use "from side" when it is in portrait/vertical format. the Torso will be shrunken.

I highly suggest to use this anatomy-lora at 1.0-1.5 strength to get rid of weird limbs.

Yes she will sometimes have pubic hair. you can try to de-prompt it.

Strength: sweetspot seems to be 0.8

If Flux generates to much limbs:
anatomy lora.

prompting:

this image shows one girl and one man. 

viewpoint is from side/above/ POV / from above. it is a close-up of anal sex scene. 

the girl is half turned away from the camera, her face turned to the side but still partially visible. she is glancing over to the viewer. she is on her knees in a doggystyle position on all fours, her anus and pussy visible. a nude man is kneeling behind her and is deeply penetrating her anus with his large penis. her ass is turned to the man. the upper body of the man is not visible. she is having anal sex with the man. the image shows a backview of the girl, clearly showing how the penis of the man penetrates her anus. 

she has a perfect ass. there is no hair under her pussy.
