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.
Most people have cut the cable cord, don't watch broadcast TV, and a lot have gone to paid streaming, such as Netflix, Amazon Prime, Disney+, etc.
All those streaming services have recommendation algorithms to suggest shows that the viewer might be interested in, and keep them hooked on that service.
Sex and violence certainly grab attention quickly, so algorithms push those more than anything else.
