No, and people come off as pretty weird when porn is such a significant part of their life and so frequently on their mind that it's their chosen pastime and conversation topic. It suggests an imbalance in how much porn is a part of one's life, when it's totally fine for it to play a large role, but not so large that you feel a strong urge to bring it up even when it makes most people uncomfortable.

I would never shame someone for consuming (large amounts of) porn, but if someone thinks about it so much that they are frequently bringing it up in average settings even though it makes many people uncomfortable, that's honestly pretty rude. And if someone knows that's the case and still feels a strong urge to do so, I think that demonstrates an issue with how and how much they are thinking about it.

If you find someone or some online community that intentionally welcomes that, lean into it and enjoy. Outside of that, exposing others to conversation they'd rather not have is not cool, likely to put distance between you, and pretty selfish. If you can't resist, that's a whole other issue.
