How do you adjust First person? And no, I don't mean fov!

[Guest]

My first person pov is in the sims head and I'm honestly tired of it. I use custom heads so it isn't the camera's fault. But I do feel like there should be a way to adjust camera placements for first person pov and no, I do NOT mean fov. I want to be able to push the camera forward and backwards, side to side, and up and down. Hence the word, adjust. Is there a mod that allows me to do this or a way to edit the game so I can do this?

What do you mean by "Custom heads"??  I didn't know using custom body parts was EVEN POSSIBLE
