Could Expired Lubricant Used At The Anus Lead To An Infection?

Hello. I just accidentally used a little bit of expired (3 years) water based lube in my anus. Thankfully it was only a little bit, and I immediately tried removing it as much as I could. I was wondering if it could cause any kind of infection down there, and how I could treat it if so. Mind you, nothing else went up there before I realized it was expired, just the lube.
