How would you feel ??

My husband and I were watching a movie and a sex scene came on the screen and I felt him thrusting with the guy on screen and not just once he went back and forward at least 3-4 times before I asked him what he was doing. It really bothered me as he’s had a problem with porn and much more stuff. I asked him what he was doing and he looked at me like I was crazy and said he wasn’t doing anything…I’ve been gaslit by him in the past so I was sure he was acting dumb like he didn’t do anything but he’s really sticking to it and sure he didn’t do anything but I know what I felt…he was humping during the sex scene and I’m sure of it. He’s made me feel so crazy for accusing him of things in the past even when I had concrete proof he straight up denied but this time I’m sticking with it. I know what he did and I know I didn’t like the way it made me feel so I’m not just brushing it off..I guess I’m just bringing it here to make sure I’m not being crazy and I’m right to feel the way I do.
