Imo... when this happens I'd ask, is it the hobby, is it the product quality, is it the repeats, or is it me.
You can get bored of sex. If sex with civvies or outside the hobby isn't boring, then that ain't it. You can get bored of p4p. If it's the script and the time limits, possibly see someone who doesn't have a script for a longer time.
It can be the same girl routine. I've had some amazing atfs who always went out to serve me properly, and I'd sometimes get bored. I'd take a break with them and return after a month or two. And it'd be amazing again.
It can be overall lack of variety. Sometimes you want that new p or new unknown excitement. That's when you take a stab in the dark go fro a storefront or a pd girl, maybe a black/white girl, someone you dont see on a regular basis.
It can be overall lack of talent, although I'd say at least service-wise there are still some good choices here in the bay for now. But it's a lot worse rn in terms of choice than like 2-3 years ago. Hopefully covid vaxxing mitigates that.
My point is. There are many ways things can get stale, from getting tired of routine to tired of same women. I think if you identify and isolate what is it that makes it mundane, you'll be able to fix it.
Cheers
