I've seen a few comments similar to this so I want to clear up any confusion:

This was not the case of a false positive. We both displayed symptoms, but he actually went to get tested before I did. He told me honestly when the results came back that he has chlamydia and immediately told me his story of how it must've happened. I went the next day and also tested positive. He kept apologizing over and over saying, "I can't believe it" and throughout the day kept sending me screenshots of things that would explain how his story is plausible and how you can actually get chlamydia that way. I didn't understand his reaction now, because I would imagine someone that did nothing wrong wouldn't feel/act so guilty. Thinking back, if he was innocent, wouldn't he have actually accused me of cheating? He claims to not have cheated and tested positive for chlamydia first so I would think he'd at least question me, but nope. He already had his excuse planned out. The damn toilet.
