<human>: Can you succinctly summarize the text in 1-3 sentences?

So, basically, we've been together 2 years and both assured one another when we started the relationship that we were STD free. She was in a long term relationship before me, and I had been tested before sleeping with her (except for one sexual partner beforehand in a one off, completely protected situation).

Only thing is I get a burning sensation when I pee now and then. I know this is quite common and could be un-STD related but I want to get a chlamydia test JUST to get that worry out of my head, but don't know how to approach this with the gf.

Just for clarification, I have not cheated and I know her well enough to know she hasn't either, but I fear that in bringing it up it may make her think 'Why now after 2 years would he want to get a test done?' and could put unnecessary doubts in her head. The other option is to just get the test done and not say anything, but then if it DOES come up with something then obvssss I have to tell her and then it seems even MORE suspicious that I hadn't mentioned anything beforehand.

What's the best way to approach this situation?
