Unless you have visibility into a niche corner of youtube that nobody else does...

Is there content on YT that could possibly be called porn? Sure. Is there actual porn the way most people understand it? Not more than a vanishingly small amount that would be next to impossible to find without getting directly linked to it.

YT doesn't even allow gratuitous posing, especially lingering rear shots, for try-on hauls. Sex talk (no explicit activity) is allowed, but put behind their "inappropriate" warning. I haven't seen anything that isn't at least dual-use educational or ASMR. I haven't seen anything that's particularly vulgar, even if it didn't descend into problematic fetishes. Plenty of YT channels were banned for suggestive sexual ASMR, even without nudity or explicit roleplay. They don't have as much problem with scantily clad, suggestive dancing in mainstream-approved media content though.

The most nudity I've seen allowed on YT was in fringe dance performances and very occasionally in mainstream music videos.

There is a huge piracy community on YT that occasionally includes porn.

Finding it is a bit hard as they move around a lot and Google is getting better at removing them, but they are definitely there.

Does that include LGBTQ content? If yes, then this probably go under the definition of intolerance and in California there are protections. YouTube should not be allowed to filter the content like that, it must have it readily available for all audiences.

It has nothing to do with sexual orientation or claimed gender, and everything to do with what body parts are shown and what explicit words (or other sounds) are used.
