I find with man and bitch porn the main difference is how devoid of interaction from the bitch the vast majority of the porn is. Anyone watching man and bitch porn could be forgiven for believing a bitch just lays or stands there quietly the entire time while the human bangs away. While I imagine there are some bitches like that out there I've not had that experience. Every one of the thousands of bitch fucks I've engaged in has seen the bitch interact clearly with varying degrees of excitement, noise and movement with me usually having to let her have several crazy moments running around before things are finished. We're constantly moving around, swapping positions, I'm constantly reacting to her movements and excitement letting it guide when I should pound harder, slow up or when I know she just needs a moment to get some crazy out. Its passionate and utterly wild. Its a completely different world from what I see portrayed in porn.
