I have had annual STI screenings for the last three years - and all tests have come up clear - until two weeks ago, when a (
urine) test for Chlamydia came up positive. All other tests negative (Syph, Gon, Hep ABC, HIV, HSV1+2). I have had only one regular female partner in all this time (who has made no complaint of vaginal discomfort), though i have also received perhaps half a dozen hand jobs at a massage parlor over the last twelve months.
