There are so many great comments from women here explaining completely rational thought processes and you just can’t seem to get past your own insecurity.

She had a sex life before you. Get over it. She doesn’t want to be fucked into oblivion by you because maybe it that doesn’t actually turn her on. Get over it. She was filming herself, of course she’s going to act like a porn star, that’s the point. Maybe she actually enjoys your meaningful, calmer sex because the intimacy makes her more fulfilled than getting railroaded does. Get over it. And if you can’t, then good riddance.

Honestly, she’s winning in this situation. If you can’t get over yourself she is 100% better without you. She did absolutely nothing wrong. I hope she knows that your insecurity is the problem here and not her.
