Whoops...

We had protected vaginal sex last night around Midnight when we got home, and I didn’t go pee because I physically didn’t feel the need to. I woke up around 8 and went pee as I normally do whenever I wake up. It burned a little bit I think that’s because I was a little raw by the end of our fuck session. I’ve never had a UTI but I know that you can get one if you don’t pee after sex. What are my chances of getting one and how soon will I know if I have one?
