Okay well in my eyes that’s totally cheating, but whatever. If this is your first time being unfaithful to this girlfriend and you’ve been with her for longer than like 4 weeks, then she also has chlamydia and gave it to you, because you don’t start to feel the symptoms for at least a week. Also crazy to me how in the TL;DR you didn’t mention cheating on your girlfriend. Even if you don’t consider it cheating, I’d bet she would.
