you get chlamydia from having sex with someone that has chlamydia. either in their genital tract mouth or anus. either one of those tests are wrong (not likely) or someone is not telling the truth. chlamydia does not just magically develop from risky sexual activity. having unprotected anal sex and then having unprotected vaginal sex is risky for infection since the rectal area is laden with intestinal bacteria. germs that are not welcome in the vagina. if you know in your heart that you have not had sexual activity with someone else then need i say more?
can you get chlamydia from anal sex then vaginal sex? . ? i have been with my partner for almost 3 year he was my first and i was his first. when we first became sexually active we both got tested and everything came out fine. we recently went to get tested again and i came out positive with chlamydia and he didn't. we do have unprotected anal sex and switch to vaginal sex. so my question is if he doesn't have it and i've never cheated could i have gotten it from having continuous unprotected anal sex?
