How did i get chylmidia but my boyfriend of a year test negative? i haven't had any sexual contact with anyone besides him. why don't we both have it?

Talk to boyfriend: You need to have a discussion with your boyfriend about your mutual expectations of this relationship. Not all laboratory tests work all of the time.

You boyfriend had it: It is harder to culture from the male so if you have not been with anyone else you had to have gotten it from him, and he obviously got it from someone else either while you have been going out with him, or he could have gotten it from someone before he met you, so time for him to man up and tell you the truth or time for u to move on, obviously your decision.
