You must be new on Earth.
Religions want more humans in their religion, so they only encourage PIV reproductive sex. Anything else, including LGBT, loses them potential babies, so they're 100% against it - and always will be.
Porn is one of those things that cause happiness, stability, and freedom of choice. So, religions fight against it as if it were COVID in the public water supply. Arranged religious marriage is the only way to get any sex without religions stepping in and harming anyone outside their control.
It's exactly the same as it was in the 70's & 80's, with religious groups fighting against paper and film pornography. Before literally everyone figured out that religions are just full of shit, control freak assholes because of the internet.
Religions ARE offended by porn. Even straight porn. They always have been. Even while they're physically raping small children, priests will still stand up against the fictional evil that is porn.
