Over the years my "flavors" change. I have a lot of porn from long ago, and none of it really works for me anymore. Used to like a lot of lesbian stuff, hentai, movies with more "production value," now I'm more into amateur, suction dildos, wet pussy, whatever.
So while I'm leaning towards a specific type of porn (usually a couple/few years) I don't really get tired of it. Over time my tastes change and I seek greener pastures.
One thing I do is get lost down a rabbit hole of "related videos" on streaming sites; I've found a lot of stuff that way that I didn't know I would be into, but now I'm a fan.
There's more porn out there than any one person can ever watch - no reason to worry if things get stale, just watch something else.
