I tested positive for chlamydia and had been with only my b/f of 9 months. He tested negative. I could have had it before then but after 9 months he STILL is negative. So how does that happen. I haven't ever had anything before that. We were in Mexico for a week prior to the test, in and out of hot tubs. I also found where the bacteria that causes chlamydia may be in dairy products also. Am I grasping at straws.. Damn right, I haven't been with anyone else and in 9 months he didn't get it. Doesn't sound right to me. I would think I was unfaithful if I wasn't me..
