Sounds like the algorithm has you in a box or sex and violence. We all get put in these boxes if you watch even one violent/sex video as the algorithm knows sex and violence gets engagement. You have to watch, like, comments whatever you can to engage with content you prefer to slowly change the feed. Even then, you will be tantalized with that sort of content from time to time as it tends to be what engages most. Resist and if possible tell it to stop showing content like that.
