Don't see a point in this debate. Porn is porn, just people fucking. Doesn't matter if it's Category A of people fucking, Category B of people fucking, or subcategories B-1 or B-2 of people fucking, you're watching people fuck and are not a participant, that's really the only point. You use your hand to replicate the physical act of sex while watching other people have sex. Doesn't matter what flavor you like, at the end of the day, all porn viewers are in the same boat as each other.

"self inserting" and lone female is a lot better for you mentally, but if you truly did that, you wouldn't need porn depicting sex at all. You're standing on a fine line to voyeurism/netorase whenever you view porn with sex and other men, and are conditioning your brain towards an unnatural viewpoint of sex. I would just stay away from it.
