In my youth, we had bendy paper straws that worked well. Probably no longer available with plastic so ubiquitous.
I'd suggest if you're going to need a plastic straw that you grab some now and keep re-using them. By the time they finally wear out/break down there are likely to be other options. But I'm surprised that one of the bent metal ones aren't an option for you.
ETA: There _are_ bendy silicon ones --
