I recently had a chlamydia test done and the results are positive. And I've been with my b/f for over a year now. I know that I did not cheat on him at all in this relationship and I know he didnt cheat me. But perhaps I got chlamydia from past relationships. I've been with more than one guy before i met my b/f. He's only been with one other girl besides me. So if it was from a past relationship why did I turn up positive now and not before? Also, are there other ways of contracting chlamydia besides from sex?
